A few improvements: 1. No signages at the airport that the porter airline was a codeshare and i could check-in at American counter. 2. Crew at the gate said they couldn't change my reward to Alaska - despite that being done previously 3. Despite there being many open seats, i was assigned a seat at the very back near lavatory, last row. Fortunately, the pilot wanted more people moved up so the flight attendants moved me up. It seemed very odd to have been stuck in last row with very few people nearby..

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!

Much roomer than air Canada! Great flight for the price. No complaints

As a first time flyer with Porter I was happy with the service and comfort of the airline.

Other than wifi no on board entertainment. Will use them again, roomier seats than other airlines and snacks and beverages, better than average

I like it, but the food isn't good. They need to offer more simple things. This bowls that have so many things your don't know what your are eating. The milenials like it, no the rest. And last but not least, they allowed somebody have a huge dog, vey agressive and fidgety in the flight. That's horrible. No animals should be allowed inside the airplane, what about allergies, etc

The flight was half empty yet they charged me $50 for a basic carry on! I saw how passengers of different colors were treated differently.

There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

Three hours on the tarmac with almost zero communication from the cockpit. Not when offered a water in the interim. In my 67 years of flying all over the world the worst experience ever. The plane was half empty, however had to pay for seats to sit next to my girlfriend. Extra to take a carry on. I would never fly Porter again even for free.

Flight was delayed over 2 hours, then landed at a different airport!

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

one of the flight attendants on the Dallas to frankfurt leg was somewhat rude..

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

A little bit more leg room in premium economy. I am 6’4”.

Sucks ! All three flights I was on this trip were delayed.

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

Food wasn’t very good, old business seating configuration on an old A340

Crew is way too many times on the intercom re explaining the same thing

Nothing. I flew business class. I always try to avoid air Canada because it’s the worst airline and it’s proven on international level. Sad and embarrassing…

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

It was good no problems made it on time for the next flight overseas!

Not impressed. Only allowed one carry on on such a long flight.

INDIGO connection is extremely bad.. will never book QATAR flight with Indigo connection.. I spend more money on Qatar flight to get better service but Indigo connection is worst than local flights

need to improve management and air hostess services. Rest of it’s OK.

Very Old flight. I didn’t expect to see this old flight. The entertainment system was very poor for a 15+ hours flight. The staff was amazing and food could is no bad could be better.

No attention paid to passengers asking for simple things such as water. Only 2 meals throughout a 16-hour flight. Crew Needs to pay better attention to flight attendant call buttons.

the seat was not padded at all - uncomfortable after a 3 hour flight

This flight was of course delayed because American cannot have flights that are not delayed.

I sat at the airport all night from 8 pm until midnight. The airline kept delaying the flight. They also kept moving us to different gates - 4 times. Then they told us we didn’t have a pilot so we had to wait. Then they cancelled the flight at midnight! I ended up having to rent a car to drive home. So i ended up not even being able to fly on the flight i paid for. Ridiculous, and no agents could help at all. I will not ever book this flight.

Mechanical delay > Crew Time out. No communication to passengers. Crew time out was positioned as a surprise (even though it must have been know at the time of boarding that the crew would time out.

Upgraded to first class. I would consider the first class on that plane to be only slightly more comfortable than coach. Long delay.

How is it that every American flight from DFW to IND is significantly delayed? This is the third time in two months I have been delayed flying out of DFW - ALWAYS for a maintenance issue. Makes me want to drop flying American altogether…or maybe flying through Dallas. Miserable experience.

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

We were delayed due to a mechanical issue, but the gate staff and then later captain were giving thorough and frequent updates. Ended up being delayed about an hour, but we did get out, so it was overall a good flight!

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Finnair is a really good airline! We specifically looked for them on this trip. On time, great crew, and overall great experience.

My experience with Air Canada was good. Great customer service… only a few delays and issues with the tunnel to exit the plain. I did not appreciate that we arrived at terminal D and had to go to terminal E to get the bags/ luggage.

Never flew with AirCanada before. Was a super duper flight every time and on time! No changes or delays!

I paid for an exit row seat but it did not have a TV. Pretty bad for a 4 hour flight

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

My flight was great! Gate attendants and crew were great… pleasant and in good spirits. Flight delayed several hours and we were well informed of the status while on plane. Thank you!

The crew was very nice and accommodating. The food needs work. My reservation was changed several times which was not comforting.

Baggage transfer process was not done properly between Air Canada flight and Swiss Airlines.

This was the worst flying experience I’ve had in the last 10 years.

There was about 65 minutes delay but there was no announcement about the delay until 5 minutes before take off.
