A very comfortable flight, an additional wash room could have made it almost perfect.
A very comfortable flight, an additional wash room could have made it almost perfect.
Look, I understand that Kayak doesn't know I cancelled my flight on Porter. So I didn't actually fly yesterday. My main disappointment is with Porter ticket fare policies, and maybe you can pass this on to them: At my employer's request, I had booked a full fare ticket with no change fees since my trip to Toronto would likely be extended. Indeed, when I went to change my flight home to a later date, I was told the Fare Difference would cost an additional $550. So much for no change fees lol! While I had the agent on the line, I hopped over to Kayak, searched for new flights on the date in question, and saw a one-way ticket that got me home for only $355. So I got reimbursed about $450for the unused half of my roundtrip and bought a new ticket for $355. What good is a full fare / no change fee ticket if they screw you with "fare difference" BS. I'm still flying home on Porter Airlines but they just lost a hundred bucks with their stupid shenanigans.
I flew with Porter yesterday and overall had a positive experience. The flight was delayed, but the airline did a good job keeping passengers informed with frequent updates throughout the process. My biggest challenge was actually in Terminal 3, where the speaker system wasn’t very clear. It was often difficult to hear the announcements, which made it harder to follow updates at the gate. On board, the experience improved significantly. The aircraft felt very new and well maintained, and the seats were surprisingly comfortable for a short-haul flight. One of the flight attendants seemed a little disengaged, but the other was excellent—friendly, professional, and a pleasure to interact with. Despite the delay, the comfortable aircraft, clear communication from Porter, and positive onboard service made for a good overall experience.
It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.
Organization and the adjusted times but the snacks could be of a bigger portion
The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.
Due to mechanical problems it was delayed causing problems the actual flight. Was fune
Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.
Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.
Porter, like most airlines, need to improve their baggage policies. In reality, there are no longer 'cheap flights' because passengers pay exorbitant baggage fees.
Crew were welcoming, accommodating and they worked hard to find places for all carry on.
very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before
It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised
My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.
lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.
My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.
My flight was delayed by a whole day, so I lost a day of my vacation.
Wifi wasn't working on one of the UA flights after boarding.
Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.
Great crew, friendly. Found the trip long just sitting with no onboard entertainment
Everything was excellent except the breakfast was cheap yogurt and cake ????
My flight got Delayed due to the airline. The attending Crewe in Montreal were not super helpful and I arrived 13 1/2 hours late from my original arrival time. Air Canada lost my luggage, they stated they booked me a hotel room overnight at no fee, however when I arrive to the hotel, there was no reservation. It also took me three different attempts to get the hotel, even covered by Air Canada as they were arguing that they were not responsible for this, despite it having been delayed due to the airline. Overall, the service was very very poor and what should’ve been a short five hour trip turned into a 13 1/2 hour saga with me, spending a night in a random airport overnight due to Air Canada’s errors, and searching for my luggage until 2 o’clock in the morning. I will never fly Air Canada again.
The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.
The Flight Attendant was particularly helpful to my wife, who was having a bad day.
It is air Canada so leaving 20 minutes late is very acceptable
One United employee a little impatient, also on flight WiFi was out for some time. I was happy to receive a complimentary alcoholic beverage for volunteering to check my carry on bag.
Everything was great, staff, planes, at the gate. All around everything was a pleasure flying .
I COULD NOT GET ON THE FLIGHT BECAUSE THE AIR CANADA CHECK-IN STAFF COULD NOT CHECK ME IN NEITHER COULD THEY DIRECT ME TO THE ALTERNATIVE CHECK-IN AIRLINE I DIDN'T FLY AND HAD TO REBOOK ANOTHER AIRLINE, PORTER FOR THE FOLLOWING DAY. I NEED MY REFUND FOR THE RETURN LEG
When a person pays 500 $ for one way ticket that person should have better seat not the seat before the bathrooms.🤔🤨
Seating is very tight. We were delayed 90 minutes to board, because the flight crew were late
This may have been the hottest cabin temperatures I have experienced on any flight prior to take off lasting for approximately 30 minutes. I am not typically one to complain but I was genuinely worried about the health of several passengers on the flight due to the extreme temperatures including a small toddler.
Air conditioning was out for about 15 minutes that made it uncomfortable. WiFi went out halfway into the flight. Flight was about 45 minutes late.
Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.
Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.
The flight was on time and crew were nice, seats were tight and there was entertainment available
Good service, friendly staff. Food was average for airlines and the seats were small.
Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.
Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.
lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints
Incompetent crew at the boarding counter. Never flying AA again.
