Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though
Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though
Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something
Horrible! No blanket or pillow available! We had bulkhead seats but the seats were worn out and no cushion old. No meal or even a sandwich for our 5 hour flight just a little bag of pretzels. Crabby attendant female with long brown hair. We will not book Alaska Airlines again
I do wish the the actual airplane I flew on was bigger. But, I made it work.
I loved that we boarded orderly and quickly, that I had an opportunity to check my bag free at the gate, that there was plenty of seat/leg room, there was smooth takeoff and landing, the attendants were pleasant and helpful, and that we arrived on time!!
We were in first class. Food was surprisingly good. Boarding was easy. Seats were lumpy. No video screen ...really? Service was good. Phone support was good
The staff and crew were excellent. The entire flight process was so friendly and smooth.
flight was canceled. don't cancel flights if you want a better score.
Missed connection due to waiting on tarmac for gate. Rebooking took 30 minutes in line with 2 people in line in front. Horrible inefficient careless staff.
The flight was canceled and very little help given at the check in desk. Everyone at the desk says: just go on the app and see how they rebooked you. I mean come on it’s embarrassing customer service.
Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.
There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2
I want to single out flight attendant Mitch who was in the Premium Economy section. When my wife’s hearing aide dropped through the cushion under the seat he was able to locate it and return it to her. Food was a different matter. Dinner was fine. Breakfast was another matter. They had a yogurt dish that the ran out of and the alternative was not very good according to those we talked to.
5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.
Great flight! Only complaint I had was that I didn’t get breakfast that morning because I don’t eat eggs for breakfast.. I ate an energy bar I bought in the airport which I had never done before. Otherwise, another great Delta flight!
The entertainment and wifi mostly didn't work on this flight.
Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.
I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us
This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.
Seats are much much more comfortable than United, which is what I usually fly
I was unable to get a check im and get a boarding pass. I tried at the desk of the flight operator Alaska, was told to go to Hawaiian and almost had to go back to Alaskan. In the end inwas told to go thru security and directly to the gate without checking in. It would have been more helpful to have the details rather than walking all over the terminals trying to check in.
Good except that I couldn’t change seat and made me wait untill I checked in
Traveling with my 90 year old mother, the boarding process was great, the gate crew was very helpful and friendly. One of the flight attendants was kind enough to assist her to and from the restroom mid-flight and cater to any requests she had. I wish I flew Hawaiian Airlines more often, it was a great trip!
We were delayed at the SD gate for close to an hour before we were allowed to depart for SJ. Reason given was inadequate ground crew to move the plane from the gate.
Thanks to the supervisor Jose my pregnant wife and our family will not miss a very important ultrasound tomorrow. What he did was simply heroic. He needs to be promoted and praised. Please tell him our family appreciates him so so much!
Your crew shortage delayed departure by an hour resulting in us missing an event we had scheduled for that afternoon outside of Fresno.
Tried using the check in email that Kayak sent out and it wouldn’t allow me to check in. It took me about 40 minutes on a chat with Alaska Airlines to get the proper link to get my boarding pass.
It was not a good experience. When I went to check-in one of Alaska's employees told me I had to check-in with Hawaiian Airlines, which was on the opposite side of the airport. I made my way over and when I got to Hawaiian Airlines they told me I was in the wrong place. The employee saw the look of defeat in my face and was able to get someone to check me in and text me my boarding pass. I had to make my way all the way back to the other side of the airport and barely made my flight. I think it would be very helpful for employees to be more informed with these Hawaiian flights that are operated by Alaska so they are not rerouting people to the wrong terminals. Also, clear signage in the check-in area.
Both flights were late 2+ hours with ZERO communication from the airlines or their staff. No offers for compensation. WiFi didn’t work for streaming and they said to only use browsing but that didn’t work either. Waste of $$. No drinks only boxed water or apple juice. No snack. One of the worst flight experiences I’ve ever had.
The ticket and bag check in was chaotic at SEATAC. No clear communication or signage for bag drop off.
Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.
It would have been nice if they had offered more than one set of snacks
Seats were not too comfortable; it was impossible to locate the underseat power outlet.
You get what you pay for with JetBlue. Every little thing costs more, you are nickel and dimed until the end. Entertainment doesn’t function. Flight attendants do the bare minimum.
The check in and boarding process was a bit of a cluster. Two people at the counter to check in, three random lines that nobody knew which was for what, and people kept getting shuffled from one line to another for no apparent reason because then they’d get shuffled back and end up getting out further back in the line than they were originally. I only had to hand my already checked bag over and it took 45 minutes. I was never assigned a seat so when I tried to board I was pulled out of line again while someone had to try to manually assign me a seat. During the flight I got up to go to the bathroom, and there was an attendant in the aisle offering pillows etc and it was a 30 min wait unbuckled standing by the bathrooms because she said I couldn’t go past her. First and last time flying jet blue to be honest.
Communication since no reason or explanation was given for 3 hrs delay
Flight was delayed several 3 hours - no reason was given and no communication what so ever.
No overhead baggage room even though I was seated in row 2. Consequently had to check in my carry on bag. Baggage carousel was jammed. Took 45 min to get my bag.
Excellent from start to finish. All staff members were amazing!
Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.
Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.
This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.
Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.
Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless
Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.
Long 5 hour and 45 min flight and only one drink service and cookie snack
Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times
I miss the screens they used to have for the long flights. I use a Kendal and it doesn’t work well with there WiFi. I tried my cell and the wifi was not good for it either this is the free wifi.
It was nobody’s fault - but the plane came 4-hrs late and we were updated randomly in 20-30 mins increments which left us hostage to sit and wait expectantly. It was very long and got very late. Our plane didn’t land until nearly 1 am! Also the toilet wasn’t working. The hosts were nice enough but were clearly “about to pass out” as one told me. Lastly, there was no snack or even time for it. Just a bad experience overall.
One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.
