Sun Country Airlines Baggage Rules and Fee Guide

Source-focused editorial review BaggageBase prioritizes official airline, baggage calculator, conditions-of-carriage, and aviation-authority sources. Variable or unclear rules are identified in the guide.

Sun Country Airlines Baggage Policy and Fee Guide

Understanding the Sun Country Airlines baggage policy is essential for keeping travel costs low and avoiding unexpected fees at the airport. Sun Country operates as a low-cost carrier, meaning baggage rules, dimension caps, and weight restrictions are strictly enforced across all routes.

Sun Country Airlines includes one free personal item with every base fare. Overhead carry-on bags and checked baggage require paid allowances, with prices set dynamically based on your route, travel season, and purchase channel. Reserving your bags online during initial booking yields the lowest rates, while adding bags at the airport counter or departure gate incurs maximum pricing penalties.

How BaggageBase Checks This Information

BaggageBase cross-references low-cost carrier guidelines by analyzing published terms, airline conditions of carriage, fee schedules, and airport sizer standards. Dynamic pricing models mean that exact dollar quotes vary per flight segment. We continuously audit baseline dimensional boundaries, maximum weight caps, military exemptions, and equipment policies against official carrier documentation to present verified operational parameters.

Sun Country Personal Item and Carry-On Rules

Every traveler flying on Sun Country Airlines is permitted one free personal item. Personal items must fit completely under the seat directly in front of you. Acceptable personal items include small backpacks, purses, totes, laptop bags, and briefcases.

Overhead carry-on bags are not included in Sun Country base ticket prices. If you want to bring a full-sized carry-on bag for the overhead compartment, you must purchase a carry-on allowance.

When evaluating options, understanding personal item vs. carry-on differences helps prevent unexpected repacking or charges at the gate. Sun Country strictly calculates carry-on dimensions including outer hardware, such as wheels, spinner feet, and side handles.

Size and Weight Limits

  • Personal Item: Maximum size is 17 x 13 x 9 inches (43 x 33 x 23 cm). There is no explicit weight limit published, but the bag must fit under the seat without obstructing aisle access.
  • Overhead Carry-On Bag: Maximum size is 24 x 16 x 11 inches (61 x 40 x 28 cm), including wheels and handles. Maximum allowed weight is 35 lbs (16 kg).
Baggage Category Maximum Size (Inches) Maximum Size (Metric) Weight Limit Fee Status Placement / Rule

Sun Country Checked Bag Fees and Weight Restrictions

Sun Country charges for all standard checked luggage unless you hold eligible military status or qualify through an active credit card benefit. A standard checked bag must satisfy specific weight and dimensional boundaries to avoid excess charges.

  • Standard Checked Weight Limit: 50 lbs (23 kg) per bag.
  • Standard Checked Size Limit: 62 linear inches (157 cm) total (calculated as Length + Width + Height).

Dynamic Pricing and Purchase Channel Tiers

Sun Country utilizes a dynamic pricing structure for baggage fees. This means the cash cost for carry-on and checked bags depends on flight demand, route length, and seasonal timing.

The most influential factor under your control is when you purchase your allowance. Fees escalate in clear tiers based on your purchase timing:

  1. Initial Online Booking: The absolute lowest price tier available.
  2. Post-Booking Online (Pre-Check-In): Higher than initial booking, but significantly cheaper than airport rates.
  3. Online Check-In Window (24 Hours Prior): Standard online rate applies before reaching the airport terminal.
  4. Airport Ticket Counter: Substantially higher flat charges assessed when checking in at the desk.
  5. Boarding Gate: The highest fee tier. Non-compliant personal items or unbooked carry-ons identified during boarding incur full gate fees.
Purchase Channel / Timing Fee Tier Level Currency Scope Cost Mitigation Strategy
Initial Online Booking Lowest Rate USD ($) Systemwide Reserve bags during initial flight checkout
Post-Booking (Pre-Check-In) Standard Online Rate USD ($) Systemwide Add bags via Manage Booking before check-in
Online Check-In Window Elevated Online Rate USD ($) Systemwide Complete payment prior to arriving at airport
Airport Ticket Counter High Counter Rate USD ($) Systemwide Pay online to avoid counter surcharges
Boarding Gate (Non-Compliant) Maximum Gate Rate USD ($) Systemwide Pre-measure items to prevent gate charges

Sun Country Overweight and Oversized Bag Fees

Bags that exceed the standard 50 lb (23 kg) weight cap or 62 linear inch (157 cm) size restriction trigger heavy excess penalties in addition to the baseline checked bag fee. These penalties are charged per direction.

Overweight Fee Tiers

Sun Country divides overweight penalties into two distinct weight bands:

  • Overweight Tier 1 (51 to 60 lbs / 23 to 27 kg): Subject to a Tier 1 overweight surcharge on top of the base checked bag charge.
  • Overweight Tier 2 (61 to 100 lbs / 28 to 45 kg): Subject to a higher Tier 2 overweight surcharge on top of the base checked bag charge.

Oversized Fee Thresholds

  • Oversized Checked Bags (63 to 80 linear inches / 158 to 203 cm): Charged an oversized luggage fee in addition to the baseline checked bag fee.

Absolute Acceptance Limits

Sun Country enforces strict upper thresholds for checked luggage. Bags exceeding these caps will not be accepted for travel under any circumstances:

  • Maximum Weight Cap: Any bag weighing over 100 lbs (45 kg) is strictly prohibited.
  • Maximum Size Cap: Any bag measuring over 80 linear inches (203 cm) is strictly prohibited.
Condition Dimensional / Weight Threshold Fee Category Acceptance Limit / Action
Standard Checked Bag Up to 50 lbs (23 kg) / 62 linear in (157 cm) Standard Base Fee Accepted without surcharge
Overweight Tier 1 51–60 lbs (23–27 kg) Tier 1 Surcharge Accepted with Tier 1 fee
Overweight Tier 2 61–100 lbs (28–45 kg) Tier 2 Surcharge Accepted with Tier 2 fee
Oversized Bag 63–80 linear in (158–203 cm) Oversized Surcharge Accepted with Oversized fee
Excessive Weight Over 100 lbs (45 kg) Prohibited Strictly Rejected as checked baggage
Excessive Size Over 80 linear in (203 cm) Prohibited Strictly Rejected as checked baggage

Comparing Sun Country Baggage Allowance to Other Low-Cost Carriers

Evaluating Sun Country against competing budget airlines illustrates critical differences in overhead carry-on weight limits and checked baggage thresholds.

While airlines like Spirit or Frontier enforce overweight surcharges starting at 40 lbs or 41 lbs, Sun Country allows a full 50 lbs (23 kg) for standard checked luggage. However, Sun Country caps overhead carry-on weight strictly at 35 lbs (16 kg). Reviewing Allegiant Air baggage rules or reading the Frontier Airlines baggage policy provides necessary context when planning low-cost travel.

Airline Free Personal Item Size Carry-On Weight Cap Standard Checked Weight Limit Overweight Threshold
Sun Country Airlines 17 x 13 x 9 in (43 x 33 x 23 cm) 35 lbs (16 kg) 50 lbs (23 kg) Starts at 51 lbs (23 kg)
Allegiant Air 18 x 14 x 8 in (45 x 35 x 20 cm) 25 lbs (11 kg) 40 lbs (18 kg) Starts at 41 lbs (18 kg)
Frontier Airlines 18 x 14 x 8 in (45 x 35 x 20 cm) 35 lbs (16 kg) 41 lbs (18.5 kg) Starts at 42 lbs (19 kg)

Traveling with Children: Strollers, Car Seats, and Nursery Gear

Sun Country Airlines accommodates families traveling with infants or young children by offering specific allowances for essential nursery and travel safety gear.

Free Stroller and Car Seat Checking

When traveling with an infant or child, Sun Country permits parents and guardians to check:

  • One car seat free of charge.
  • One stroller free of charge.

These items can be checked at the main airport ticket counter before security or gate-checked at the aircraft door prior to boarding. Gate-checked strollers and car seats are retrieved at the jetbridge or tarmac upon arrival at your destination.

In-Cabin Infant Restraints and Diaper Bags

  • Diaper Bags: A diaper bag counts as a standard personal item. If a traveler carries a purse or backpack in addition to a diaper bag, one of those items must fit within a paid allowance or fit beneath the seat alongside the diaper bag.
  • In-Seat Safety Seats: FAA-approved child restraint systems (CRS) and hard-shelled car seats are allowed in cabin seats provided a separate ticketed seat has been purchased for the child.

Sun Country Special Baggage: Gear, Instruments, and Pet Travel

Specialized baggage, recreational items, and pets follow distinct transport rules under Sun Country Airlines guidelines.

Sports Equipment

Most sports gear-including golf bags, ski/snowboard equipment, and fishing gear-can be checked as standard luggage provided it weighs 50 lbs (23 kg) or less.

  • Golf Bags & Ski Equipment: Oversized linear fees are often waived for standard protective golf or ski bags, but standard overweight fees still apply if the bag exceeds 50 lbs (23 kg).
  • Surfboards & Large Equipment: Surfboards and large water sports gear are subject to oversized bag fees and space availability in the aircraft cargo hold.

Musical Instruments

  • Small Instruments: Items such as violins, flutes, or small guitars may be brought into the cabin as a paid overhead carry-on, provided they fit in the overhead bin and space is available when boarding.
  • Large Instruments: Cellos, large guitars, or brass instruments that exceed carry-on dimensions must either be checked in a durable, hard-shell case or carried in-cabin on a separately purchased seat.

In-Cabin Pet Policy

Sun Country permits small dogs and cats to travel in the passenger cabin on select domestic flights for a non-refundable pet fee per direction.

  • Pet Carrier Rules: The pet carrier counts as your free personal item and must fit underneath the seat in front of you (maximum carrier height is typically restricted to 9 inches).
  • Limits: Pets must remain fully enclosed inside the leak-proof, ventilated carrier for the duration of the flight. Cargo pet transport is not offered.

Gate Sizing Rules, Bag Drop Cutoffs, and Airport Rules

Sun Country enforces strict operational timing and airport checks to ensure on-time departures.

Airport Sizer Box Enforcement

Gate agents actively monitor carry-on luggage sizes during boarding. Personal items are checked using metal sizer units (17 x 13 x 9 in). If a personal item does not fit comfortably into the sizer box, or if an overhead carry-on exceeds 24 x 16 x 11 inches, agents will mandate that the bag be gate-checked. Gate-checked items incur the highest possible fee tier.

Baggage Drop Cutoff Times

Passengers checking luggage must complete bag drop procedures prior to strict airline cutoff deadlines:

  • Domestic Flights: Baggage counters close exactly 45 minutes prior to scheduled departure.
  • International Flights: Baggage counters close exactly 60 minutes prior to scheduled departure.

Arriving after the baggage cutoff window results in rejected luggage, even if you hold a valid boarding pass.

Cashless Airport Ticket Counters

Sun Country airport check-in counters operate on a cashless basis. Any baggage fees, overweight penalties, or administrative charges paid at the airport must be processed using a credit card, debit card, or approved digital payment method. Cash is strictly rejected at airport ticket counters.

Before you fly

Follow these practical packing and preparation steps to lock in the lowest rates and prevent gate penalties.

  • Pay for Bags During Initial Booking: Reserve carry-on and checked luggage allowances when buying your flight ticket to secure the lowest dynamic fee.
