Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Flight delayed due to ground hold. Republic airways did a great job.

The flight was smooth, the crew was great but the plane was quite old

Flight was warm for first few hours and quite rough

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

The flight was oversold and they kept on announcing they were looking for a volunteer to give away their seat, but the announcement has to be louder and clear @ gate 88 and also must precise. Additionally, the departure time kept on changing. But overall it was fine since it was a short flight.

I received the two differed meals: chicken and pasta. I asked and I received. I am anti-wasting food!

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The entertainment wasn’t playing in the app or online.

Biggest problem for me is that I am Star Alliance Gold and they were not able to give me access to to Maple Lounge because of some computer glitch . It was management by information system. She could clearly see my status and still would not give me access because the computer woudl not let her. She should have override that be attentive to a customer and figure rhat out later

Flight got canceled last minute and rescheduled 3 days later, as if we do not have jobs and children to return to. 5+ hours on hold with customer support with no answer. We booked a different airline and spent 3x as much to escape Montreal bc of Air Canada. Still haven’t heard from them. Boooo

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

One of the flight attendants was very attentive to a couple traveling with a child under 1 one year old.

My flight has been canceled and I had to cancel entire trip.

I’m 5’3 115 lbs and felt so cramped in this express jet. My carry on actually meets the requirements and still had to be stuffed Into the overhead and barely fit down the aisle. Not a great experience. Air Canada needs to replace these planes.

My wheelchair was sent somewhere else, it wasn’t at my ending destination.

The plane used on this flight didn't have a working air conditioner. It was extraordinarily hot and uncomfortable.

Slight delay with arriving flight but explained and still made our destination on time

Both flights were delayed in taking off. The flight to Montreal was delayed by several hours. We also sat on the runway for quite a while for both flights.
