I have a 48hr trip to Budapest from Stansted next month, and I plan to carry a normal backpack well within the carry-on dimension limits of other non-budget airlines.

It looks like the small-only policy wasn't followed as strictly per the posts above, but the last message above is more than 3 months old, so just wondering if anyone has recent experience of how strict they are with normal backpacks which aren't exactly the official allowable tiny size?

Admittedly I expect my normal backpack to be only half full, but good to know nevertheless.
