Business class should have free wi-fi. Food was horrible
Business class should have free wi-fi. Food was horrible
Will never fly American Airlines business class again. Medicore service and very old aircraft.
The flight crew has really upped its game.
Staff went above and beyond with their care for us. Flight attendants were very attentive to our needs. Food seemed too rich and too salty. Flight was fine, even with turbulence at points.
Crew members were excellent.
It all went very smoothly, love the new planes and cabin crew upbeat and friendly Food ok, but that is the hardest part of it all
Amazing crew, safe and clean plane. Downsides were related to WiFi that only worked 3h in a 12h flight and I paid for entire flight and the food that was too intense, nothing clean to eat. Route was a little bumpy during most of the time.
Finnair was ok. But some things were pretty bad: 1. Crew was not friendly, especially a crew member named, Maria. She woke me up while I was deep asleep by force just to let me know that 2 people can’t be on the same seat (my toddler and me) for sleeping. 2. There was no vegetarian option in the menu so I had to eat bread for one meal 3. They didn’t have an option for child meal
Short comfortable flight. Like many European and US based airlines - expect a budget airline experience even on full service airlines
