Food is delicious I’ve tried Thai green chicken curry and it was perfect!

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

The booking I made 2 months in advance got changed the week before with another flight and had to pay more for seats and luggage. Not to mention hours and hours on hold to make sure my flight is still booked.

The United Airlines crew that operated this flight was subpar. They didn’t

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Checkin took along timen only.few angents available at.checkin desk. Customer support over phone no existence

The crew was caring and attentive in making my flight comfortable as I was travelling with an injury.

The entertainment screens need to be updated. Very difficult to navigate through with old equipment.

You cancel my flight in the morming and I have only one hour for my transit for Cluj this is not too much

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.
