Lynda was rude and unhelpful. We asked for tea wiht a slice of lemon. She served us Coffee instead. When we spoke to her she made it seem as if we were lying. I asked if she would like to taste it and see - her reply was I don’t need to be rude. After this incident we were treated with subpar service for all beverages and food items after. We’re were purposely left out when they did garbage collection.

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes

I paid for a comfort class seat and was seated in economy.

Very smooth flight and the crew members were very welcoming.

All good, but plane outdated, seat uncomfortable, food that we had was 4 out of 10. Crew was great!

Lack of crew staffs to handle emergency medical situations that ending no meal served and only hot water and bag of pretzels served for business class!

Very Poor Even with the disruptions our flight was delayed twice then eventually cancelled. Subsequently we to this date have lost 3 days of our vacation. The situation still remains unresolved
