I was surprised how good an American airline can be - I was really impressed.

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

It was so hot on the plane. No air jets above the seats

Over all experience was good. However the connection time was too short at CPG. We missed our connecting flight to AMS as the passport control line was too long and by the time we got our passport control done it was too late I wish there were some SAS staff to help us out at the passport control center Though they put us in a KLM flight from CPG to AMS, That flight was also delayed by over two hours

I paid for my seat 💺 assignments for all for legs of my trip, SFO thru Copenhagen to Prague and back the same way. It cost 💲216.00 USD for all four seats. Despite this, on my return 2 flights, my prepaid seats were given away. When I spoke with the information services professional, she said she could not help me, nor provide an alternative seat equivalent or better than what I had. When I spoke with another representative, she was very rude, disrespectful, and did not help.

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.

The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

Really like this airline. Best food for airlines and comfortable seats and attentive staff. Delay was due to air traffic.

Baggage was mis-handled; food and grocery items in the baggage were damaged.

It was a good flight. Everyone was professional and the flight was smooth.
