The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The flat beds. Other than that, the place was not clean.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

Flight delayed and we were forced to check our carryon bags which was huge inconvenience.

First leg delay, rescheduled second leg without our approval, cancelled rescheduled second leg, rescheduled cancelled leg to three days later...

We were seated in the rear of the plane. Buses arrived to take us to the terminal but there weren’t enough so we waited an hour to leave the plane.

Every flight was late in arrival, last was late in departure and late in arrival, then lost our luggage!

They canceled the flight and would not rebook us within several days

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!
