Airline Luggage Allowance Checker — 50+ Carriers, Carry-on and Checked Rules, Excess Fee Estimate

Real-world use cases

• Catch a 4 kg overage on a Spring Airlines ticket before you leave home

  You booked the cheapest Shanghai–Bangkok fare on Spring Airlines, which gives 20 kg checked and weighs carry-on hard. Your case reads 24 kg on the bathroom scale. Type 24, pick Spring economy, and the line says 「4 kg over, about 60 RMB per kg at the counter」. You move two shoe boxes into a 6 kg tote and walk up at 19.5 kg instead of paying 240 RMB at the desk.

• Pick the right carrier for a two-suitcase move to Dubai

  You are relocating and need to fly 46 kg of stuff one way. Comparing Emirates economy (30 kg, one ticket) against a US carrier on piece concept (2 bags of 23 kg) decides the whole booking. The checker shows Emirates covers it on a single weight allowance while the piece-concept carrier would flag a heavy-bag fee on the second case. You book Emirates and skip a 150 USD surprise.

• Settle a business-class baggage question for a client trip

  Your manager flies Cathay business to London with two sample cases plus a suit bag, roughly 60 kg total. Open Cathay, pick business, and the table shows two pieces at 32 kg each, so 64 kg is inside the allowance with the suit bag as carry-on. You forward the source link from the row so the travel desk approves the booking without a back-and-forth email thread.

• Write an accurate "before you fly ANA" guide as a content creator

  You are drafting a Japan travel post and need the real ANA economy numbers, not a number you half-remember. The catalog gives 23 kg checked, 10 kg carry-on, 158 cm linear, with the ana.co.jp source URL beside it. You quote the figures, link the official page for your readers, and pin the snapshot date so the post stays honest when ANA next adjusts the limit.

Common pitfalls

• Reading the total weight allowance as per-bag. Asia and Europe economy is often 「20 kg total」, not 20 kg per case. Two 15 kg bags are 10 kg over, not fine.

• Trusting one carry-on number across an itinerary. A codeshare uses the most restrictive segment, so a 10 kg ANA limit can drop to 7 kg on the partner leg. Check every operating carrier.

• Assuming overweight and oversize are one fee. They stack. A 25 kg case that is also 165 cm linear can trigger both a heavy-bag charge and an oversize charge on the same piece.
