Although airports and airlines have had some time to prepare, it is likely that the new measures could cause confusion and delay for passengers.
This is particularly true for travellers coming from outside Europe (where rules are not as strict) who could face confiscations of private items and duty-free purchases if they are oversized or not presented in appropriate, tamper-proof bags.
Passengers could even encounter problems related to rule inconsistencies in Europe, as countries are free to adopt stricter measures than the EU minimum rules if they wish.
The new measures will also lead to increased processing and screening costs in airports, although these costs might be partly offset by increased sales of drinks and snacks in airport shops and on flights.
Tighter rules on carry-on luggage will also undermine a recent push by budget airlines to reduce costs by encouraging passengers to bring only hand luggage onto planes and to check in online.
