First time flying and stressing a bit. I’ve got a Heys Zen carry on that was gifted to me, and after measuring it, it’s about 1.3cm over Cathay Pacific’s listed carry on size.
Is that basically a guaranteed problem, or are they flexible with something that small? Will it still fit in the overhead bins on most Cathay flights, or am I likely to be forced to check it?
Would appreciate any reassurance or real world experiences.
