FAQ
What bag size can I take across several airlines?+
Every airline caps your free bag differently, so on a multi-airline trip the safe size is the smallest of them all. The Trip Checker takes each airline’s largest free allowance and shows the one size that still flies free on all of them.
I’m flying Ryanair and Wizz Air — what’s the biggest free bag?+
Both cap the free bag at their under-seat size, so a bag around 40 × 30 × 20 cm flies free on both. Anything larger needs Priority or a paid cabin bag. Select them above to see the exact shared size and bags that fit.
Does it account for weight limits?+
Yes. When the airlines you pick enforce a weight limit, the Trip Checker uses the strictest one so you stay within every airline’s rules.
