I had an episode of anxiety over very minor turbulence which I sometimes get and both ladies who happened to be on duty were very reassuring and sympathetic to me. I had my 6 year old daughter also on the plane who is not anxious at all, so I was able to speak to one of the staff in French so as not to transfer my anxiety to my daughter who doesn't understand French. This was great. Over half way through the flight they gave me some earphones and suggested I watch a movie. This helped so much.

The crew and their sincere attitude to be of help. Wonderful team of professionals.

One hour delay, which was very tiring for someone who already had gone through the 9 hour flight torture from Athens. The Global Entry for US bound passengers procedure is very confusing. Maybe it would help if the steps were communicated on the US bound passengers before disembarking. First the passport process (easy) then there is this confusing process where we need to see our names in green on the screen, with some staff telling us to move on while others insist that we need to stay back and wait for our names to go green on screens that keep changing. Good idea and intentions to help clear bags, and can be improved. Overall the Montreal to DC flight (with the exception of the awful Montreal airport and the long delay) was excellent.

Flight cancelled due to weather, the workers made it seamless.

Had to tack on extra expenses for food while waiting for the next flight. Should have gotten some type of vouchers to cover meals at the very least during cancellations. That would be next level.

Long wait for de-Icing. Got on and off the plane 3 times. First wait was 1 hour, but plane aborted takeoff. Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home. Arrived 8.5 hours after schedule.

The earlier flight departure times are really good, the traffic is not jammed yet on the 401 and GEW. Custom waiting times are basically non existing in comparison to Pearson. Planes are relatively on time (only flew 4 times with Porte), staff is friendly. The turboprop planes have more legroom than most others. I do like them, and do recommend Porter.
