Dulles, like Seattle has a tram. That can be surprising. The TSA at Seattle is notoriously LONG, however, both times in the last year that I have flown, that has not been the case. At Dulles, the TSA lines were efficient as well. The airport interior is well marked for getting around. I did note that the garbages were full in the Southwest and Alaska areas- as we were there 6 hours and had lots of time to notice nit-picky things that nobody else would care about :). It was convenient to have a "charging station" nearby the Alaska waiting area (right across from our gate). It had 3 ports, and I noticed that as soon as I unplugged mine, it was jumped right on. Suggestion- have Dulles add a few more for passengers who need to recharge phones. Great experience, thank you.

Delta by far is a great airline, they’re fast and great staff. I just wish they had a little more snacks

It was all great all around. Will travel with Alaska next trip.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

Flight 351 SEA to BOI was terrible. We got to cruising altitude and I needed to use the restroom but the fasten seatbelt sign never came off. There was no turbulence and I'd felt the plane level off so I stood up to use the restroom about 15 minutes after we leveled off. The stewardess went over the intercom and said I needed to be seated because the captain hadn't turned off the fasten seatbelt sign....Which... Fair.... But not five minutes later she went and used the bathroom. Felt very unprofessional to leave a paying customer with a burning urethra for the entire flight and bark at them to sit down and still use the bathroom yourself. They never did turn off the seatbelt sign.

For longer trips, snacks are puny, boring and don’t have ANY nutritional value.

Upgraded to first class both times .The flight attendant Spicy Tim.was excellent and very amusing.

Close boarding too early we’re willing to not let people on flight that could not check in. What ever happened to customer service? Three of us had to fight to get on plane shameful

Check your emails that you sent me. 9 emails were sent telling me that my flight is Delayed. Each one with a different time 7:10, 7:55, 9:31, 9:09, 9:29, 9:44, 10:00, 9:49, and 10:10. That was how my experience went.

Made us check our carry on,even though there was plenty of room because they didn't check with the flight crew. Also boarding was 40min late, due to the plane being on the wrong side of the airport. Also their app didn't record my tsa precheck

The flight was delayed due to a safety check. Why couldn't that have been done ahead of time? We got to Seattle with enough time to make our connecting flight but they kept changing the gate so we missed it. There were at least ten of us who missed the flight. The airline was aware. They could have waited. They didn't. Our new flight was not for seven hours and then was delayed another two hours. We got the last seats which don't recline. Super uncomfortable after a long day spent at the worst airport. Did they offer us a meal voucher or anything? On top of that Alaska Airlines didn't complete my ticket to the new flight. I wasn't sure I would get on this horrible flight, either. Oh, and it's ten o'clock at night....no food. Is this how Alaska Airlines treats its customers? I'll never fly with this airline again.

It was very comfortable. Personal entertainment screens would, of course, have been nice. And the flight in Seattle was delayed, but... things happen. All in all, I like Alaska Airlines very much.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

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.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Flight left early and arrived early. the whole trip was excellent.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

The departure gate was changed from C1 to B18 but it was never announced at the C1 gate nor did I receive any email or text message or phone call about the gate change. I was in a window seat. In the other two seats next to me were Mr. Rotund and Ms. Rotunda, a youngish couple. Just the two of them should have booked three seats. I was smashed up against the wall and window for five hours. Overall, I'd say my flight sucked. Wouldn't you?

I couldn't get checked in 24 hours before either leg of my flight. I tried both my Alaska and Hawaiian codes on both apps.

We moved from the international terminal to a new location. I think there are still some bugs to work out . We didn’t receive check in notification and had to scramble to find it but i think it will work out

I'm was impressed with their service. Everything was great

All in All a great experience. Cost of luggage sucks … first time I ever had to pay for luggage. Otherwise the check in counter was awesome, the gate clerks were great and the Stewards & Esses were the best.

As my daughter was boarding the flight they pulled her from the line and told her, after she had checked in and checked a bag, that she could not board the flight due to a fraud flag on the debit card used for the ticket purchase. The personnel would not allow me to speak to them, saying I had to take it up with customer service that was not present. They tried to get my daughter to purchase another ticket on the spot or get out. The customer service personnel were insistant that the personnel at the gate be on the phone which they would not allow. Would not accept payment from three different accounts and did not resolve the issue. Many conflicting reports about the source of the problem, the fraud department is uncontactable. The only good thing to come of it was checked bag arrived. Our family will not be using Hawaiian Airlines. Ever.

Great staffing. Terrible food. Please do cold sandwiches or salads. the "hot pickets" are terrible.

Love Hawaiian you can’t go wrong, still provides you good drinks and little snack at the end

No tv’s. Had to walk 45 minutes to connect to next flight. Couldn’t get dinner as a result. Ended up eating pretzels until I felt sick.

Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

leg space better than expected. two washrooms for one plane isn't enough.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

Liked nothing. As per previous segment it was delay delay delay.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The flight was initially delayed, then cancelled. American Airlines says the cancellation was weather related, though the actual weather was not bad in both Washington and Providence and between. There were very few cancellations that day. In fact, AA2120 from Washington, DC to Boston flew with a minor delay at about the same time. So, the weather somehow affected only this particular flight AA5230. The next available flight was the following morning. The American Airlines refused to reimburse accommodation (hotel at DCA)

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

Good experience but the snacks are not gluten free, so I cannot eat them.

Standard. No different than a discount carrier on a short trip.

Everything was great. Boarding, early departure, early arrival, and deplaning were smooth. Smooth flight.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

I blame kayak for my last trip to dca. Kayak cancelled my direct flight and put on a one stop flight and made lost whole day from my vacation and had not even refunded my ticket.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

I had two wonderful flights - very relaxing and got me there early!
