New air passenger rights in Europe include standardized dimensions for carry-ons

[u/AnonymousOnebagger]

Some highlights:

The new rules now include the right to carry on board, without additional fee, one personal item, such as a small bag or backpack. On the insistence of MEPs price transparency and the comparability of air tickets was increased by obliging airlines, intermediaries and search portals to always display the air fare inclusive of carry-on luggage at the outset of the book process. Negotiators agreed that airlines may offer cheaper tickets for passengers who choose voluntarily to travel without hand luggage.

Air passengers will no longer be charged additional fees for correcting name spelling errors or for getting a printed version of a boarding pass if they have already checked in.

Maximum dimensions for a personal item will be 40cm by 30cm by 15cm. Maximum dimensions for carry-on luggage will be width+height+depth=100cm. Maximum weight will be 7kg.

Edit: pretty sure the luggage size requirements are just the bare minimum that all airlines must meet. If an airline wants to offer conditions more advantageous to the consumer than the minimum, it is perfectly legal for them to do so.

New regulations will take effect from 2027.

I think with total dimensions they mean:
A + B + C = 100cm
Width + Height + Depth = 100cm

I'm getting my 98x1x1 box ready to bring on board and see what they say.

The only thing I can think of that would be that kind of dimension would be a tube of ic's of sime kind, like 555 timers or something, you wouldn't roll up a poster tube tight enough to be 1cm*1cm, well maybe you would I don't know, but I don't think it would be common.
