Denver Air Connection Baggage Allowance and Fee Guide
Denver Air Connection, operated by Key Lime Air, provides regional passenger air service connecting Essential Air Service (EAS) communities to major U.S. aviation hubs, including Denver International Airport (DEN), Dallas/Fort Worth International Airport (DFW), Phoenix Sky Harbor International Airport (PHX), and Chicago O'Hare International Airport (ORD). Unlike major U.S. mainline carriers that charge for every checked bag on domestic routes, Denver Air Connection includes a free checked bag on standard published fares. However, because the airline operates a fleet of smaller regional aircraft, cabin overhead bin space is strictly limited, requiring specific gate-check procedures for standard carry-on suitcases.
Denver Air Connection (operated by Key Lime Air) allows each passenger one free personal item under the front seat and one free checked bag weighing up to 50 lbs (22.7 kg) within 62 linear inches (157 cm). Passengers may bring one carry-on bag, but due to small regional aircraft overhead bins, standard rollaboard suitcases are usually valet gate-checked free of charge during boarding and returned planeside upon landing.
Baggage Allowance Snapshot
Denver Air Connection provides one free checked bag up to 50 lbs and one free personal item on standard fares. Overhead carry-on items are permitted but are usually valet-checked at the boarding gate due to regional aircraft size limits.
What can change: Interline bookings through United Airlines or American Airlines, space-available cargo constraints on small regional aircraft, and baggage added at the airport counter.

Official Source Verification
Baggage rules can vary by fare, cabin, route, operating carrier, traveler status, and purchase channel. BaggageBase separates published rules from practical guidance.
How BaggageBase Checks This Information
BaggageBase cross-references policy data against official airline tariff filings, contract of carriage documentation, airport customer service guidelines, and regional fleet operations manuals. For regional air carriers operating under Essential Air Service contracts, allowances and weight restrictions are systematically evaluated against aircraft performance caps to ensure data accuracy.
When reviewing regional air carriers, conditional variables-such as interline codeshare agreements, planeside gate-check policies, and space-available excess cargo rules-are explicitly isolated. BaggageBase continually verifies operational details against carrier publications to provide accurate guidelines for travelers.
Carry-On and Personal Item Rules
Denver Air Connection permits ticketed passengers to bring cabin baggage on board, but the size and storage method depend heavily on the aircraft type operating your route.
Personal Item Allowance
Every passenger is allowed one free personal item that must fit beneath the seat directly in front of you. Acceptable items include small backpacks, purses, laptop bags, briefcases, or small totes.
While official carrier documentation specifies under-seat fit rather than explicit linear dimensions, standard dimensions across the fleet average approximately 17 x 10 x 9 inches (43 x 25 x 23 cm). To review general cabin rules across carriers, see our detailed guide on what counts as a personal item. For a broader look at cabin bag definitions, read about understanding the difference between a carry-on vs. personal item.
Overhead Carry-On Baggage & Regional Jet Limitations
Passengers are allowed one standard carry-on bag measuring up to 22 x 14 x 9 inches (56 x 36 x 23 cm). However, Denver Air Connection operates regional aircraft-including the Fairchild Swearingen Metroliner, Embraer EMB-120, Dornier 328JET, and Embraer ERJ-145. Cabin overhead bin space on these aircraft is narrow or nonexistent.
Because standard rollaboard suitcases and large duffel bags cannot fit inside the overhead bins of these regional aircraft, the airline utilizes a mandatory planeside valet check procedure (also called a "skycheck" or ramp check):
- Gate Tagging: When you arrive at the boarding gate, airport agents will attach a pink or yellow valet tag to your carry-on luggage.
- Planeside Drop: You carry your tagged bag down the jet bridge or boarding stairs and place it on the luggage cart directly outside the aircraft door.
- Cargo Stowage: Ramp workers load your valet bag into the cargo compartment just before departure.
- Planeside Retrieval: Upon landing, your valet bag is unloaded immediately and handed back to you on the tarmac or jet bridge as you exit the plane.
Critical Safety Rules for Valet-Checked Luggage
Because valet bags are stowed in the main cargo hold during flight, you must remove key personal items before handing your bag over at the aircraft door. Never place the following in a valet-checked bag:
- Spare lithium-ion batteries, power banks, and electronic nicotine devices (vapes).
- Critical prescription medications and medical equipment.
- Passports, identification cards, credit cards, and cash.
- House and vehicle keys.
- Delicate, fragile, or high-value electronics (laptops, cameras, tablets).
Place all essential items and spare lithium batteries inside your under-seat personal item prior to boarding.
Checked Baggage Allowance and Fee Schedule
Denver Air Connection provides a standard checked bag allowance that is significantly more generous than most domestic regional airlines.
1st Free Checked Bag
On standard published fares purchased directly through Denver Air Connection, passengers receive 1 free checked bag included in the base ticket price. To meet standard allowances, your free checked bag must adhere to two hard caps:
- Maximum Weight: 50 lbs (22.7 kg)
- Maximum Dimensions: 62 linear inches (157 cm), calculated as Length + Width + Height.
If you are trying to decide whether to pack light or check a larger suitcase, consider comparing a checked bag vs. carry-on to optimize your packing strategy.
Additional Checked Bags & Space-Available Limits
Passengers who need to bring extra luggage can pay for additional checked pieces at the airport check-in counter. However, because small regional aircraft operate under strict weight and balance restrictions, 2nd and 3rd checked bags are accepted strictly on a space-available basis.
If an aircraft reaches its operational payload limit due to fuel requirements, weather conditions, or passenger volume, excess luggage may be held for a subsequent flight.
| Baggage Category | Weight Limit | Maximum Dimensions | Fee ($ USD) | Availability & Conditions |
|---|---|---|---|---|
| 1st Checked Bag | 50 lbs (22.7 kg) | 62 linear in (157 cm) | $0 USD | Included free on standard fares |
| 2nd Checked Bag | 50 lbs (22.7 kg) | 62 linear in (157 cm) | ~$30 – $45 USD | Space-available basis at airport check-in |
| 3rd+ Additional Bag | 50 lbs (22.7 kg) | 62 linear in (157 cm) | ~$50 – $100 USD per bag | Strictly space-available; no space guarantee |
Overweight and Oversized Baggage Surcharges
When a checked bag exceeds standard weight or size allowances, Denver Air Connection assesses additional surcharges at the airport check-in counter.
Linear dimensions are calculated by adding the total outside length, width, and height of the suitcase ($L + W + H$). The official source does not clearly state whether wheels and handles are included in linear measurements, but standard aviation practice measures maximum external dimensions.
Overweight Surcharge Tiers
Bags weighing over 50 lbs (22.7 kg) incur an overweight surcharge based on total weight:
- Tier 1 Overweight (51–70 lbs / 23–31.8 kg): Assessed an overweight surcharge of approximately $35 to $50 USD.
- Tier 2 Heavy Overweight (71–100 lbs / 32–45.3 kg): Assessed a heavy surcharge of approximately $50 to $100 USD, subject to strict weight and balance clearance.
- Maximum Limit (Over 100 lbs / 45.3 kg): Bags exceeding 100 lbs will not be accepted as passenger baggage.
Oversized Surcharge Tiers
Bags measuring between 63 and 80 linear inches (160 to 203 cm) incur an oversize surcharge of approximately $50 USD. Any piece exceeding 80 linear inches (203 cm) will not be accepted as standard passenger luggage.
| Condition | Weight / Dimension Threshold | Surcharge Fee ($ USD) | Acceptance Limit & Action |
|---|---|---|---|
| Standard Checked Bag | Up to 50 lbs (22.7 kg) | $0 (1st bag) | Included in standard fare allowance |
| Overweight Tier 1 | 51 – 70 lbs (23 – 31.8 kg) | ~$35 – $50 USD | Accepted with overweight surcharge |
| Overweight Tier 2 (Heavy) | 71 – 100 lbs (32 – 45.3 kg) | ~$50 – $100 USD | Subject to space-available weight clearance |
| Excess Overweight | Over 100 lbs (45.3 kg) | Not Accepted | Refused as passenger luggage; cargo freight required |
| Oversized Bag | 63 – 80 linear in (160 – 203 cm) | ~$50 USD | Accepted with oversize surcharge |
| Excess Oversized | Over 80 linear in (203 cm) | Not Accepted | Refused as passenger luggage; cargo freight required |
Interline Connections with Partner Airlines (United & American)
Denver Air Connection holds formal interline ticketing and baggage agreements with major U.S. carriers, including United Airlines and American Airlines. These partnerships allow passengers to book a single continuous itinerary connecting a regional airport to national and international destinations.
Determining Which Airline Rules Apply
When your journey involves a transfer between Denver Air Connection and a major airline partner, baggage policies are governed by interline ticketing regulations:
-
Single Interline Ticket: If your route is booked as a single electronic ticket issued by United Airlines (ticket numbers beginning with
016) or American Airlines (ticket numbers beginning with001), the baggage allowances, fee structures, and elite status exemptions of the primary marketing carrier may govern your journey. - Through Luggage Check: On single-ticket itineraries connecting through major hub airports like Denver (DEN), Dallas/Fort Worth (DFW), Phoenix (PHX), or Chicago O'Hare (ORD), your checked luggage is usually tagged through to your final destination at your initial departure airport.
- Separate Tickets: If you purchase a Denver Air Connection ticket separately from a United or American ticket, you are traveling on two independent contracts. You must retrieve your checked bags at the intermediate hub airport's baggage claim, re-check them at the connecting airline's ticket counter, and pay any applicable baggage fees for each airline separately.
Always review the baggage fee section of your official e-ticket receipt to confirm which carrier's baggage allowances apply to each segment of your trip.
Military Benefits, Infant Gear, and Special Equipment
Denver Air Connection provides specialized exemptions and handling rules for active military members, families traveling with young children, passengers requiring medical assistance, and sports enthusiasts.
Active Duty U.S. Military Allowance
Active-duty U.S. military personnel traveling on military orders or personal travel receive expanded checked baggage allowances upon presenting a valid active military ID card at the airport ticket counter:
- Military Allowance: Up to 2 free checked bags weighing up to 50 lbs (22.7 kg) each, subject to space availability on the aircraft.
Infant and Child Equipment Rules
Families traveling with infants and young children benefit from dedicated baggage equipment exemptions:
- Lap Infants: Infants traveling on a parent's lap do not receive a separate checked baggage allowance.
- Strollers and Car Seats: Fully collapsible strollers and child car seats are checked free of charge either at the ticket counter or at the boarding gate. These items do not count toward your standard checked bag allowance.
Medical Devices and Mobility Aids
Mobility aids, wheelchairs, and medically necessary devices fly free of charge under federal aviation regulations:
- Wheelchairs & Mobility Equipment: Manual or battery-powered wheelchairs and mobility aids can be checked at the ticket counter or gate free of charge.
- In-Cabin Medical Items: Devices such as CPAP machines, portable oxygen concentrators (POCs), and required medical supplies are permitted on board free of charge and do not count against your personal item or carry-on limit.
Sports Equipment and Musical Instruments
Standard sports items (such as golf bags, skis, snowboards, and fishing gear) and musical instruments are accepted as checked luggage, provided they fall within standard weight (50 lbs / 22.7 kg) and size (62 linear inches / 157 cm) caps.
- Surcharges: Items exceeding 50 lbs or 62 linear inches are subject to standard overweight or oversized surcharges.
- Space Constraints: On small regional aircraft, large equipment cases (such as hard golf travel cases or large ski bags) are accepted strictly on a space-available basis.
What Happens if Your Bag Exceeds Limits at the Airport
If your checked bag exceeds weight or dimension restrictions when placed on the scale at the airport ticket counter, airport agents will apply the following procedures:
- Repacking Opportunities: If your bag exceeds the 50 lb (22.7 kg) weight threshold, ticket counter agents will allow you to open the bag and transfer items into your under-seat personal item or split contents into a second bag (subject to 2nd bag fees).
- Space-Available Rejection: If an oversized or overweight bag cannot be safely accommodated due to the aircraft's weight-and-balance limits, the carrier will refuse the bag for that specific departure.
- Key Lime Air Cargo Alternative: Freight or personal items exceeding 100 lbs (45.3 kg) or 80 linear inches (203 cm) cannot fly as passenger luggage. These items must be consigned through Key Lime Air Cargo freight services prior to departure.
Denver Air Connection Airport Readiness Checklist
Use this checklist before leaving for the airport to handle regional aircraft bin constraints and baggage weight caps smoothly.
- Verify Checked Bag Allowance: Confirm your ticket qualifies for the standard 1st free checked bag up to 50 lbs (22.7 kg).
- Mind Airport Cutoff Times: Check in and drop checked bags at least 45 minutes prior to departure (60 minutes recommended at DEN, DFW, PHX, and ORD).
- Prepare Personal Items for Small Under-Seat Spaces: Use a flexible, soft-sided bag to ensure a fit beneath regional jet seats.
- Pack Valet-Check Essentials Separately: Keep medications, power banks, keys, and travel documents in your under-seat personal item in case your carry-on is valet-checked at the tarmac.
- Check Interline Receipts: For connections to United or American, review your initial airline e-ticket receipt to verify if bag fees were prepaid.
- Plan Ahead for Additional Bags: Excess, oversize, or overweight bags are accepted strictly on a space-available basis due to regional aircraft cargo limits.

Summary and Final Decision Steps
Denver Air Connection provides a straightforward baggage structure designed for regional travel. By including one free checked bag up to 50 lbs (22.7 kg) and allowing a free under-seat personal item on standard fares, the airline eliminates the extra fees commonly associated with short-haul domestic flights.
However, handling cabin baggage requires preparation due to aircraft size restrictions across the fleet. Standard carry-on rollaboards will almost always be valet gate-checked at the tarmac door and placed in the cargo hold. Pack critical medications, travel documentation, keys, and lithium-ion batteries inside a soft personal item beneath your seat.
Before departing, weigh your checked luggage to keep it beneath the 50 lb (22.7 kg) threshold, and ensure extra bags are approved at check-in if traveling with excess cargo. If connecting to or from a partner airline like United or American, confirm your overall baggage allowance on your primary ticket receipt.
Airline baggage rules and fees can change by route, fare, cabin, operating carrier, traveler status, purchase channel, and departure date. Check the airline's official baggage policy or calculator before booking, paying, or traveling. BaggageBase reviews information for 2026 where possible, but the airline's published terms remain the final authority.
