The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

Everything was great except British airways lost our luggage that was gate checked all the way through to Italy. No one knows currently where one is and the other one may be in route to Amsterdam to meet us but not sure. If you can Hale’s it would be awesome. The website is not helpful.

Seats were roomy. Lavatories were surprisingly big and clean. Plenty of entertainment available. We were fed and offered drinks, multiple times during the flight.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

the pilot that landed this flight in Philadelphia did an amazing job, the weather was absolutely terrible and we landed safely.

The flight was just perfect! We left a few minutes early, had a smooth flight and fortunately had landed before the terrible accident that took off from North Philadelphia airport shortly thereafter.

Took off on-time and staff was very nice. Got stuck on tarmac at ATL due to storms, but staff was still wonderful even though they were working and not getting paid.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

The plane was filthy!!!! There were empty food wrappers in the pockets and worst of all a wad of hair where someone had obviously brushed their hair, cleaned out the brush and left the wad of hair in the pocket. It was the most disgusting thing I’ve ever seen!! The seats are so crammed together with NO leg room. The AC vent controllers do not adjust. I will likely not book another AC flight from Florida to Montreal.

This was an excellent experience for a very short flight.

Registered my luggage at 5pm. Arrived at JFK at 1:00 am. Worst trip ever. Never again

Really good, super comfy flight and the stewardess was great.

Air Canada never runs on time. You’re lucky if your flight is not cancelled or diverted. Worst airline in the world for gas lighting its customers.

No space in overhead bin, one cookie, 2 oz of juice - is not customer service.

Good flight, friendly crew and overall - good service on United Airlines.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.
