Al Italia cabin bag size

[lazysummer]

How strict is Al Italia on cabin bag size? I have just read 55cms by 35cms by 20cms. We are flying from London City Airport. My bag is 50cms by 40cms by 20cms. Do I need to buy a new bag? We are flying tomorrow!

Anyone have any experience? I havre phoned them and they have stressed weight.

I've flown with them a lot and never seen them measure a bag. It fits under your seat, right?

Thank you.
Yes it does.

I still feel nervous about it though!

It'll be ok!! When is your flight?

Flight is Saturday morning but we are staying in London this evening.

Update: no one checked! We had substituted cabin bags for holdalls, which were a pain to carry, but the correct size.Next time, I wouldn't bother!
