Someone rebooked my Alaska flight to a much later Delta flight. Now I am sitting at the Seattle airport after a long international flight and have to wait another 4 hours even though I would have been able to catch my initial flight

Someone rebooked my Alaska flight to a much later Delta flight. Now I am sitting at the Seattle airport after a long international flight and have to wait another 4 hours even though I would have been able to catch my initial flight

Very short leg - too short for any meals/snacks or entertainment.

We missed the flight. I had a passport issue and told the check in desk that I’m trying to resolve it but when I got approved for entry to USA at 3:32, one hour before departure, the employees had left the desk at 3:30. I tried calling and texting the numbers on the sign. No luck. Waited till the agents came back and couldn’t get a flight to our destination or close, so we flew to Las Vegas instead and drove 6 hrs to San Diego where I missed one night’s stay and the car rental that was reserved there. Extra car rental and hotel in Las Vegas was over $300. Lost tine and money. I wanted to extend the trip by two days but the $1600 SAVER fare wouldn’t let me make changes. Hours on the phone to find out there are no exceptions and no credit if cancelled in advance. Very disappointed. My son’s first vacation with me in 17 years. Wasted a lot of money. Next time I will use a local travel agent.

Booked a first class ticket and was not even offered a bottle of water…or a cracker…absolutely zero in flight service on a 1 hour flight

The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

Well to start the crew is Seattle told me my luggage would go right thru to Ottawa. Not so before landing we were told to pick up luggage at carousel 8. On landing I asked and was told to pick it up & take it to the conveyer to be sent to Porter. Staff said Alaska always says that but no it doesn’t happen. As for Porter they said the flight would be a bit rough, so they offered a free wine or beer. Only snacks were provided on each flight.

Boarding was late with no communication. Flight was over an hour late with virtually no communication or updates. The app showed we had departed and were scheduled to arrive on time even though we sat on the tarmac for nearly an hour. People who were using the app to track our progress to pick us up were given erroneous information. Flight attendant was snooty when asked why app was showing us as delayed and arriving on time even though we had not left and ultimate’s not leave for over an hour. Just poor and arrogant.

My luggage was lost and doesn’t appear to be arrived any time soon.

Check in was a nightmare. We had about 15 people ahead of us but were in line for 45 minutes for priority passengers. Two people were checking in dogs and it took them forever. They even took the dogs out of the kennels to weigh them separately. Crazy! Then when we reached the front of the check in line we were told they couldn’t check us in because we were too early. Had to wait 19 minutes to check in and then check ourselves in and get back in line to drop our bags. This was first class! If I can avoid it I will never fly Alaska again. I sure didn’t get what I paid for.

It would have Bern better if the flight was on time.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The cabin temperature was nice and cool. The wifi was not working.

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

First flight out and was 85 minutes delayed. Notification came out way too late

Terrible experience delays going there and delays coming back will not be flying delta

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

Both flights were late by about 30 minutes .. Other than that, everything was ok..

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Flight was good, crew was excellent. No complaints at all

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

I didn't think about not having the right app for wifi because my connecting flight was with Westjet and when I took off from Seattle I was thinking I would use my wifi, but realized I couldn't on my Westjet app and I did not have Delta's app downloaded.

Scrooge airlines spoiled my last chance at Christmas with my 95 and 92 year old folks. and rest of the family in Calgary. Ticket personnel would not let me on without a passport and I always visit Canada with my enhanced driver;s License when I travel from the US

Westjet is the worst airline in the world, they are absolutely terrible, there are to many things that happened that I can't explain in this message, I would like to talk to someone about my ordeal. I am partial handicapped and that I can only walk a short distance, I calculated how far I walked and it was more than a kilometer, the pain is so bad today I have to go to my docor, they told me there was nobody available to take me to my gate, this is just one instance. This is not finished yet, I need to contact westjet and let them know about my trip from hell

They lost our luggage and didn’t return it until 15 days AFTER we got back.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

They could care less about you. Just under a 4 hour delay in Seattle, leading into a missed connection in Vancouver, which led to 2 more delays that added up to 3 more hours leaving us to have to sleep on the floor of the Toronto airport cause they don't help you find accomodations and they just book you on the next flight out. Took an additional 14 hours to get home. Always given the brush off to get rid of us. Worst airline ever

All was good with comfort and ease of boarding. There was confusion from what gate to board at. Meant moving a long distance but I allowed plenty of time for this.

Good airport. Good entertainment on the big flight. Did not have a good way to prop up or mount my phone/ipad

Air Canada at SeaTac was the best. Polite, helpful, all good!

The problem in part was with the airports, not really the fault of Air Canada. Confusing directions regarding the gate, in Seattle the recommended shuttle train entrance was not working. Simular problems in Toronto. Baggage arrived in good time. Marx Bros movie on entertainment from Seattle. I was told I was laughing too loudly, by the flight attendant. No lounge in Seattle. Lounge in Toronto excellent.

Both fights were delayed. Food could be better comparing to other international flights

I found the personal kind and caring. The Problem was not enough people to serve the the customers. The flow was restricted the crowd frustrated by the wait times. Air Canada seems to hire good people but they need backup in order to provide the service we pay for.

The Montreal to Barcelona flight was cancelled half hour before boarding. We had to struggle for hours to find an alternative route through a very long route with 6 hours of transit time in Munich. It wasted almost one full day of our long awaited vacation. We are extremely disappointed.
