Quick Comparison Table ​

Carry-On Baggage: Size and Weight Compared ​

Your carry-on bag goes in the overhead bin. Here is how the five airlines stack up.

Biggest Carry-On Size ​

Japan Airlines and Aer Lingus tie for the longest cabin bag at 55 cm. Both are close to the standard European carry-on size.

Air Corsica is also 55 cm long but a bit narrower at 35 cm wide.

Qatar Airways allows 50 × 37 × 25 cm. It is shorter than the European carriers but wider.

Air Peace has the smallest cabin bag by far — only 45 cm long. A standard 55 cm roll-aboard suitcase will not fit.

Heaviest Carry-On Weight ​

Japan Airlines and Aer Lingus both allow 10 kg, which is the most generous limit in this comparison.

Air Corsica allows 8 kg per cabin bag.

Qatar Airways allows 7 kg.

Air Peace is the lightest at only 6 kg. That is not much — a laptop plus clothes can easily hit 6 kg.

Combined Weight Rules ​

Japan Airlines counts your cabin bag and personal item together. The total weight of both items must stay under 10 kg. It is not 10 kg per piece.

Aer Lingus sets the weight limit per cabin bag, not combined with your personal item.

Personal Item Allowance ​

This is where the airlines differ the most. A personal item goes under the seat in front of you.

• Qatar Airways — No separate personal item in economy. You get one cabin bag and that is it. No laptop bag, no handbag, nothing extra.
• Aer Lingus — One personal item up to 40 × 30 × 20 cm. They have a clear size rule. No weight limit is published.
• Air Peace — One personal item up to 2 kg. No specific size limit is listed on their website.
• Air Corsica — One personal item allowed. No published size or weight limit.
• Japan Airlines — One personal item allowed. No published size or weight limit, but it counts toward the 10 kg total.

Important: If you fly Qatar Airways, pack everything into one bag. There is no extra personal item allowance in economy class.

Checked Baggage: What Is Included ​

Checked baggage goes in the hold of the plane. The rules are very different from airline to airline.

Air Peace ​

Air Peace uses a weight system on domestic routes. You get 20 kg total to spread across as many bags as you want (as long as each bag stays under 32 kg). On some international routes like London, they switch to a piece system with two 23 kg bags.

Air Corsica ​

Air Corsica uses a piece system. How many free bags you get depends on your fare:

• Light fare: 0 free checked bags
• Standard fare: 1 free checked bag of 23 kg
• Top fare: more bags included

Each bag must stay under 158 cm total (length + width + height).

Qatar Airways ​

Qatar Airways uses a weight system on most routes. Your free baggage allowance depends on your fare type and where you are flying:

• Lite fare: 0 kg (no checked baggage)
• Classic fare: 20–30 kg total (depends on route)
• Comfort fare: more weight included

They have a very generous size limit of 300 cm linear per bag — much bigger than the standard 158 cm. Great for large or oddly shaped items.

Japan Airlines ​

Japan Airlines uses a piece system on international routes. Economy class includes two free checked bags of 23 kg each. That is the most generous economy allowance in this comparison.

Each bag must stay under 203 cm total (about 80 inches).

Aer Lingus ​

Aer Lingus uses a piece system. Your fare decides what you get:

• Saver fare: 0 free checked bags
• Plus fare: 1 free checked bag of 20 kg
• Advantage fare: more bags included

Each bag must stay under 20 kg and 158 cm total. The 20 kg limit is lower than most airlines, which usually allow 23 kg.

Fare Types at a Glance ​

Free Special Items ​

All five airlines let you bring certain special items for free that do not count toward your normal baggage allowance.

Note: "Not listed" means we could not find a clear statement on the airline's website. It does not necessarily mean the item is not allowed. Check with the airline directly if you need to bring special equipment.

How Strict Is Each Airline? ​

All five airlines have a strictness rating between 5 and 7 out of 10, but they enforce the rules in different ways.

Air Peace — They have bag sizers at security checkpoints for domestic flights within Nigeria. Weight checks are common at the check-in counter. If your bag is over the limit, you will pay excess baggage fees.

Air Corsica — On small ATR planes to Corsica, they almost always gate-check roll-aboard bags for free because the overhead bins are tiny. This is actually a nice bonus — you get to check your bag for free even on Light fares. On bigger Airbus planes, enforcement is more standard.

Qatar Airways — They weigh bags at the gate at Doha airport and on busy routes. The 7 kg limit is real — people get caught all the time. The 50 × 37 × 25 cm sizer is also strictly enforced.

Japan Airlines — The most relaxed of the five. They rarely weigh carry-on bags, especially on domestic routes. They do check size with a sizer on busy flights, but weight enforcement is light. Strictness score: 5 out of 10.

Aer Lingus — Dublin Airport has scales at every boarding gate. They weigh cabin bags regularly, especially on busy routes. If you booked Saver fare and show up with a roll-aboard, you will pay €35 at the gate to check it.
