EU chief Ursula von der Leyen said Friday there was "still quite a lot of work to do" to resolve issues with a new border check system blamed for severely disrupting European air travel.
European airports and airlines warned this week that the new Entry/Exit System (EES) was causing wait times of up to five hours, urging the EU to act now to prevent summer travel chaos.
Pressed on the matter, the European Commission chief acknowledged the rollout of the scheme -- introduced last year to register non-EU travellers entering the 27-nation bloc -- was far from perfect.

"There's still quite a lot of work to do to have these technical issues solved together with the member states," she said.
