West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

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!

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.

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

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.

They did a fine job. Can't wait to use Delta in the future.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

I liked the friendly crew and desk staff, all very helpful. I was surprised and a little annoyed on my outbound flight from LGW to MCO as I had prepaid and booked my seat, which was all correct at check in on my boarding pass. when I got on the plane someone was in my seat ! I was moved to another seat. The food choice is quite limited and I feel that an option of a muffin for breakfast snack would be welcomed, not everyone wants egg or bacon wrap. The choice of entertainment is good, plenty to keep you busy on a long haul flight. I liked the option offered to have the cabin bag checked into the hold, it saved me as an older, lone traveller lifting my case into the overhead locker or finding there was no space.

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I’m hoping for WiFi included. Everything else was very good

Both flights were delayed. I lost my connection on the way back. No voucher or anything was givenx I had business ticket and no support to make it on time. I got to the door running 5 min after they close. Food really bad. Breakfast in business was worst that I what I remember in economy. Even though I have accumulated many miles, I don’t think Inwill keep buying Iberia. I am a frequent business traveler.

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

The entertainment system got stuck in the ABBA music channel. The headsets were not loud enough. My pre purchased aisle seat was not honoured

Non stop flight from Barcelona to Rome, arriving on time.

3 hr flight from Barcelona to Gran Canaria. Ŵent according to plan No issues with staff oŕ flight. Many people includiñg us could not get luggage self checķ in termìnals to work. Had to wait in check in line.

The communication about the delay could have been better before and during the flight. Also, this online form could have less bugs. It is almost impossible to type in this window.

We got to the airport 2 hours before the flight. We waited in a line to check our bags onto the flight for an hour, even despite having checked in online, as there weren't enough self check terminals allocated to Vueling (yet loads of empty BA ones right next to them). There also weren't enough staff, making them stressed and rude. We had to try and rush through security to get to our gate, which they announced as gate 35 at first and then changed it after ten minutes with no announcement to anyone in the airport that it had changed. So we then had to rush to the correct gate to arrive just as boarding started. It was a thoroughly stressful process and one travelling couple almost missed boarding because of it. The flight boarding and the flight itself werre fine, the staff were polite, but I was dehydrated due to the airport and had to buy a bottle of water as they didn't offer free drinks.

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

You have couple of KG's grace on checked luggage

Last time bucking this company if I would know I wouldn’t do it, they made me lose my flight

The baggage policy is pathetic. We paid for our carry-on bags online. Said if we don't remove the wheels of our carry-ons it's not considered a carry-on. We all measured our bags according to the website beforehand. We were not refunded for our bags and were obligated to buy it as checked in bags for over $70 online or $90 over the counter. First and last time I travel with this airline.

Because the scale includes two terminals, we almost lost our flights. That data was not referrenced to us. The check-in process was a pain too.

We were very lucky and got a complementary upgrade somehow because the crew needed our seats.

Bordón could be bettet if the company say before boarding the order of the different groups.

Checked in is easy and it was a smooth flight from LAX to Munich

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

The Lufthansa part was wonderful. The short connection flight was not.

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

It was a busy flight and all the crew were very helpful and gracious

Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent

Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.

It was a short haul trip, so food and entertainment weren’t a big issue

The plane seemed very dated. The entertainment was very limited. There was a school group on our flight and the crew seemed bothered by them. They were not overly friendly or welcoming.

Ok, but no entertainment. Left late, but made up most of the time.

May be it is not an ITA issue, but the bags took long time to go out.

Good. But there food was poor quality and 95% of movies didn't have English subtitles

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

Service from staff was poor, food choices were limited. Air plane was not clean or hygienic and seemed like not cleaned for days. Seats were uncomfortable.

service from stAff was barely there , food choices were limited. AirPlane was not clean and seemed like it was not cleaned for days.. Seats were very uncomfortable.

I paid for premium seats and the last minute they changed the aircraft for a bigger one, they bumped me to another seat which was NOT at all comfortable for an 11 hour flight, will fight for a refund!!

The landing was catastrophic. I was very scared. I thought it were my last lminues. Pilotes should be more experienced
