Airline reviews

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

The flight was excellent, I recommend people to fly with Delta

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Airport monitors did not give the gate for our flight returning Detroit to Vancouver Juice served from glass storage containers are a far more healthy alternative for people. And would also minimize the need for recycling plastic or aluminum containers

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

I had planned to watch the Westjet entertainment for the entire flight however, because the seat mounted outlets in our row did not work.

Not a bad flight but our priority tagged luggage was the very last to come down the carousel.

Plane had a flat tire, delayed boarding and takeoff but one in the air, smooth. Make sure you have downloaded the WJ app before you leave. When on board, you can watch movies or TV shows offered on the app, it passed the time very quickly.

Our recent flight from edmontown to kahalui was excellent. The service staff was very friendly, knowledgeable, funny and attentive. Thanks to all involved that made or travel such a pleasant experience and we hope to fly with west jet again soon

The flight was delayed and I missed boarding my 7 day cruise. I had to book a separate flight home

No real issues just wasnt able to hear / understand any announcements flight attendant was making but everything else was really good- ended up checking my carry on case for free which made deboarding quicker. I would fly West Jet for all my flights.

Seats were comfortable and leg room was good. Slight delay for boarding but nothing too bad. Would fly with them again.

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Great. Porter is very efficient, welcoming, and organized. I fly Porter often.

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

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.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10 Tips for people flying porter from Boston. The airline doesn’t have inflight entertainment No TV No WIFI. Bring your entertainment with you.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10

Wasn’t on the flight- again. Bad weather in Halifax and I was in an accident. What a poor experience to have to pay for all this flight and not be on it

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.

Limited snack options cause the snack vendor was on strike

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

I didn’t like the fact that all the customs officers went to lunch so I was in line for 90 minutes due to where the staff directed me. We were told three very different reasons for why the plane was delayed. It was a crowded plane with difficult storage situations for the Carry On bags. The Air Canada airline staff were all very good and professional. I was so disappointed in my cheese and fruit box as the cheese had molded and the fruit wasn’t fresh so I couldn’t eat the majority of the food. This was the last meal I could find as the restaurants had closed when I got in to my destination. I think you could work on improving the food quality.
