Pros: The crew on the jet were fine. The entertainment was good too.

Cons: The crew at checkin we’re pretty awful. They were rude and not very helpful. I witnessed 3 customers have poor service in front of me and then they weren’t helpful with me either. The plane changed and I had paid for a seat and I lost my money and the seat I paid for and was never notified.

Excellent 8.0

Pros: The crew was nice and the movie selection was decent. Food was ok. As good as it can be when you pay $2,500 for a flight ticket knowing that they are not really there to offer you a service, they are there to make their own money knowing that as a traveler you really have no options other than an airplane if you want to go across the ocean.

Cons: Seats become smaller and smaller...and you keep asking about my experience...$2,500 to travel seating in a miniature seat with no leg room is a bit much...and I know no flight company cares about this...we have no choice...either take that or don’t travel, right?

I called Swiss as soon as I landed, and I've told my request was sent but it was never confirmed. They also told me they will send me an email when the basinet for the return flight is confirmed. At this point, I'm not even sure what I paid the $98.93 for.

Pros: We finally got to our destination

Cons: Weather delayed the flight by around 4 hours. Crew at the airport were clearly stressed and took it out on stressed passengers. You had to ask for everything rather than the crew proactively doing things to make people comfortable (regular updates, food vouchers, going around making sure people are comfortable). Captain on plane was good. Crew on plane was ok, more socializaing with each other rather than being proactively helpful.
