Aero K Baggage Policy: Fees, Allowances & Rules Explained 

Aero K allows one carry-on bag (max 10kg, 55x40x20cm) free on all fares. Checked baggage depends on fare type: Plus fare includes 20kg, Basic fare includes 15kg, and Lite fare includes none. Overweight fees range from KRW 12,000 to KRW 18,000 per kilogram depending on route, and pre-purchasing baggage online is always cheaper than paying at the airport.

Aero K is a South Korean low-cost carrier based at Cheongju International Airport, flying to destinations across Japan, Vietnam, Taiwan, the Philippines, and Mongolia. Like most budget airlines, Aero K keeps base fares low by unbundling services, which means baggage isn’t always included in your ticket price. Understanding exactly what you’re entitled to, and what it costs to bring extra, can save you a significant amount of money at the check-in counter.

What Is Aero K’s Baggage Allowance?

Aero K’s baggage allowance depends entirely on which fare you purchase: Plus, Basic, or Lite. Plus fare passengers receive 20kg of checked baggage, Basic fare passengers receive 15kg, and Lite fare passengers receive no checked baggage at all. All fare types include the same free carry-on allowance.

Here’s how the three fare tiers compare:

If you’ve booked a Lite fare, any checked bag you bring will be charged in full as excess baggage, so it’s almost always cheaper to add baggage during booking rather than assuming it’s included.

What Is Aero K’s Carry-On Baggage Allowance?

Aero K permits one carry-on bag weighing less than 10kg per passenger, with maximum dimensions of 55cm x 40cm x 20cm (the sum of all three sides must not exceed 115cm). This applies uniformly across Plus, Basic, and Lite fares, on both domestic and international routes.

In addition to your main carry-on, Aero K allows a small personal item free of charge, provided it stays within the same 10kg weight cap. Permitted personal items include:

• Laptops or tablets
• Small purses, handbags, or briefcases
• A small quantity of books or duty-free goods
• A coat, blanket, small camera, or binoculars
• An umbrella or cane without a sharp tip
• Mobility aids for elderly or disabled passengers (wheelchairs, crutches, prosthetic limbs)  these don’t count toward your weight limit

Carry-on bags must be stored in the overhead bin or under the seat in front of you. Storage is not permitted under your own seat, in emergency exit rows, or anywhere that blocks access to an exit.

How Much Checked Baggage Does Aero K Allow?

Beyond the fare-based allowances above, a few special cases are worth knowing:

• Infants under 24 months: On international flights, infants get a 10kg checked allowance plus one stroller or car seat. On domestic flights, only the stroller or car seat travels free.
• Total dimension limit: Checked bags cannot exceed a combined 203cm across all three sides.
• Group bookings: Groups of 10 or more traveling together on the same reservation receive 15kg per person, with any excess charged at standard rates.

What Are Aero K’s Baggage Fees?

Aero K charges different rates depending on whether you buy extra baggage online in advance or at the airport, and the fee also varies by region. As of March 29, 2026, pre-purchased baggage costs less than airport purchases across every route, sometimes by a significant margin.

Pre-purchased baggage fees (booked online in advance):

Gate bag fees (paid at the boarding gate):

Note that Aero K reduced the maximum gate bag weight from 20kg to 15kg as part of the 2026 fee update, so a heavier bag purchased at the gate may still incur overweight charges on top of the base fee.

How Much Is Aero K’s Overweight Baggage Fee?

If your checked baggage exceeds your fare’s included allowance, Aero K charges an overweight fee calculated per kilogram, and the rate depends on your route. As of March 29, 2026, excess baggage paid at the airport costs KRW 12,000 per kilogram to Northeast Asia and KRW 18,000 per kilogram to Southeast Asia and Mongolia.

Airport excess baggage fees:

Cost comparison example: Say you’re flying Cheongju to Tokyo on a Basic fare (15kg included) and your bag weighs 20kg  that’s 5kg over. Pre-purchasing that extra 5kg online costs KRW 40,000. Showing up at the airport with the same overweight bag costs 5 x KRW 12,000 = KRW 60,000. Booking your extra weight in advance saves KRW 20,000 on this route alone, and the gap widens further on Southeast Asian routes.

Choose pre-purchased baggage if you already know your exact packing weight before departure. Choose to pay at the airport only if you’re unsure whether you’ll need extra baggage at all, since pre-purchased weight isn’t always refundable close to departure.

What Items Are Restricted From Aero K Checked Baggage?

Aero K prohibits explosives, compressed gases, flammable substances, corrosive materials, irritants, magnetic substances, and radioactive materials in any baggage. Money, securities, precious metals, jewelry, and valuables are also excluded from checked baggage coverage, meaning Aero K won’t take liability if these items go missing.

Under Korea’s Aviation Security Act, bringing prohibited items onto an aircraft can result in imprisonment of two to five years, so it’s worth double-checking your bag before you leave for the airport, especially for connecting international itineraries.

Does Aero K Offer Online Check-In?

No. Aero K does not offer online check-in, and all passengers must check in at the airport counter before their flight. This is an important detail that catches many first-time flyers off guard, since most competing airlines allow check-in from a phone or laptop.

Airport check-in counters at Cheongju International Airport open 1.5 hours before departure and close 20 minutes prior. At Jeju International Airport, counters open 2 hours before departure and also close 20 minutes prior. Because there’s no digital shortcut, arriving early is the only way to avoid being denied boarding for a late check-in.

How Can You Avoid Extra Baggage Fees With Aero K?

The most reliable way to avoid paying excess baggage fees is to weigh your luggage at home and purchase any extra weight online before you arrive at the airport. Since pre-purchased rates are consistently cheaper than gate or airport rates, and gate bag capacity is now capped at 15kg, waiting until check-in to sort out your baggage almost always costs more.

A few practical habits to build into your pre-flight routine:

• Weigh your suitcase using a home scale before packing valuables or last-minute items
• Check your fare type (Plus, Basic, or Lite) to know exactly what’s included before adding anything
• Pre-purchase excess weight as soon as you know your itinerary, since prices only increase closer to departure
• Keep prohibited items (batteries, liquids over 100ml, valuables) in your carry-on or leave them at home

Frequently Asked Questions

What happens if my checked bag exceeds 203cm in total dimension?
Aero K may refuse to carry oversized baggage or require special handling arrangements and additional fees, since 203cm is the maximum combined dimension for standard checked bags.

Do infants get a separate baggage allowance on Aero K?
Yes, infants under 24 months receive a 10kg checked allowance on international flights plus one stroller or car seat; on domestic flights, only the stroller or car seat travels free.
