Bring your own entertainment. Depend on them for reliability and your flight to get you there on time if not early.
Verified travelerFlew with Alaska AirlinesDCA-SFOJan 2025
Reserve your plane seat & bring something to eat in the plane.
Verified travelerFlew with Alaska AirlinesIAD-SANDec 2024
I chose it because it was non-stop🥳
Verified travelerFlew with United AirlinesIAD-BUFNov 2024
Give yourself the appropriate amount of time because getting to the boarding gates takes some time due to the layout of the wait port but the signs are clear and the transportation is well organized.
PaulFlew with Alaska AirlinesDCA-SEAOct 2024
DCA is much better than IAD. I am very happy with non-stop schedules for Alaska Air. Wish there were more flights in and out of DCA vs. IAD though.
RebeccaFlew with Alaska AirlinesIAD-SANSep 2024
Get something to eat in the airport, just in case there is no food onboard.
Verified travelerFlew with Alaska AirlinesIAD-SEASep 2024
Pay the money if can afford to upgrade your seats
MilesFlew with American AirlinesDCA-PITSep 2024
Arrive early for morning flights. Even precheck and clear had a line at DCA
Verified travelerFlew with American AirlinesDCA-PBINov 2024
Just suggest that they add free WiFi on the flight
Verified travelerFlew with Alaska AirlinesIAD-SEAJul 2024
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.
PaulaFlew with Alaska AirlinesDCA-PDXJul 2024
Baggage fees for Alaska are fare - if you paid with their card it is free, and if not it is 35.00. I was happy with all other aspects of the flght both to DC and back.
Verified travelerFlew with LufthansaIAD-RDUAug 2024
Make sure, if you are flying internationally and this is your connecting flight- you have time to get through border control and you will need to claim your baggage and drop it off again.
PaulFlew with Alaska AirlinesDCA-SEAJun 2024
It's pricier to fly into Reagan (DCA), but if your destination is core DC area, it is well worth it. I used Ubers and Metro; no need to rent a car.
Verified travelerFlew with Alaska AirlinesDCA-LAXJul 2024
Easy access via metro, and by car with parking available walking distance from the terminal. Lots of seating and dining options near the flight boarding gates.
ShashankFlew with American AirlinesDCA-INDJul 2024
TSA for Terminal 2 is one level below ticketing and check in - on concourse. Indy is a well laid out and easy airport to get around.
NoamFlew with Alaska AirlinesIAD-SFOAug 2024
Flying to the Ronald Reagan airport is closer and faster to D.C. than the Dulles airport.
Verified travelerFlew with Alaska AirlinesDCA-SEAJul 2024
Alaska Air surprised me with the overall experience. I will use them again.
StephenFlew with United AirlinesIAD-ANCAug 2024
Allow more time than you initially think; it is a long way!

I would recommend Alaska Airlines. The amenities and comfort was great.

At Dulles, you can spend 30 minutes getting to your AFTER clearing TSA

Be prepared Seattle is a mess as far as the overwhelming crowds when you land . The bus line to get your rental car is unbelievably long almost 100 people so be prepared once you arrive .
OliverFlew with Southern / MokuleleIAD-BFDJun 2024
Don’t get to the ticket counter more than an hour early, no one’s there. You’re going to be waiting.
Verified travelerFlew with United AirlinesIAD-BOSMay 2024
I liked the flight . The crew staff were v . good. I liked the initial presentation on the screen rather than looking at the air hostess . Got a very back seat which I did not care for.
MarylinFlew with DeltaIAD-SEAMar 2024
Delta by far is a great airline, they’re fast and great staff. I just wish they had a little more snacks
Verified travelerFlew with SouthwestDCA-FLLMar 2024
Arrive earlier to avoid lines for baggage drop off. Also opt for baggage check in my mobile app

Get to the airport early, especially on holidays
Verified travelerFlew with DeltaDCA-MSPApr 2024
use restroom prior to boarding, hall to bathroom is small
Verified travelerFlew with JetBlueDCA-FLLFeb 2024
Fly directly into Miami if that is your final destination. Ground transportation between FLL and MIA is expensive ($50) and time consuming (1+ hour). One would think there would at least be hourly public transit between the two airports, but no such luck in the late afternoon. Choices are $50 bus ride or $50 ride share, or $50 bright line, or $50+ rental car. No afternoon Tri-Rail service. I chose the ride share since it got me directly to my downtown Miami hotel.
Verified travelerFlew with FrontierDCA-DENDec 2023
Always check the rules and guidelines prior to boarding. Be early. Rest and eat before departure.
Chaira AndreinaFlew with DeltaDCA-JFKFeb 2024
Boarding was great and crew was great 😃👍

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

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

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Delta is a premier airline so my expectations are most always met.

Seats are much much more comfortable than United, which is what I usually fly

Zero updates from the pilots for 30 minutes in the tarmac

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Compared with other carriers business class for an overnight was not worth the extra expense.

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

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.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

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.

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.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

Crew professional. Easy bag drop off. On time. Good entertainment.

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

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.

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.

No leg room AT all extremely uncomfortable flight water even cost 5 dollars

Seats are poor. They do not lean back. They do not even have pockets on the back, making it impossible to store a phone or a coke bottle. If you opt for basic economy cheap seats, they stick you always in the middle or window seat, even though there are unoccupied seats on the aisle. And then there is the nickel and diming. No carry-ons. And checking your carry-on is $70. At the end there is no price advantage but there is plenty of aggravation.

Not good. No updates regarding the flight status until after the fact on the delays and then a cancellation.

Flight crew was great. Spirit leaves a lot to be desired in terms of comfort.

This was my first experience with Spirit. The flight was originally delayed because of mechanical problems. There was a major storm moving through our area later in the day. Spirit kept changing the gate and taking the plane for other flights. They did this 6 times until we left 7 hours later, right at the worse time. I am sure it is because they originally delayed the flight through their fault. They would have had to pay for everybody's hotel and later flight. It was a money decision. The pilot did an exceptional job flying and landing the plane in horrific weather. It was one of the roughest and shakiest landings that I have ever done in my extensive flying experience. I just can never go through this discount BS again. Spirit gave us a $30 voucher each for next travel and a $12 meal voucher... but that's nothing compared to sitting in an airport for 7 hours.

Seats were comfortable but dont recline at all. Checkin online was easy but didnt provide a gate until last minute. Flight attendants were very unkind, not friendly and didnt go over safety procedures in case of a crash. No free snacks or beverages, not even water.

Good crew and safe. However, comfort and being nickeled-and-dimed are my issues. $75 each way for luggage is exhortation. The space to the next seat is so close you cannot open a laptop. The magazine rack doesn’t hold your items. Not a fan.

The booking was cancelled the next day. Spirit Airlines refunded Kayak cheapflay the full amount, but I was only refunded half. Costumer service is disgusting. Be careful. You can lose your money.

Everything on the flight was OK. However, the price is very deceiving the way that it is marketed. It seems like it’s going to be very low cost, but when you add in the charges for luggage, choosing a seat, food & drink, etc., that are already included in other competitors fares, it really is no cheaper, and possibly even more expensive than the other carriers. It actually makes your carrier seem dishonest.

If kayak actually provided me this flight and didn’t just send me notifications about it

They switched my flight to Spirit, Never using Kayak again,

i was denied boarding, even though i had an assigned seat, checked in on line and was at airport early. Then they refused to fully refund the the fair and replacement fair because they claimed it was "no show/denied boarding". I will never fly this airline again

I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.

This was a full flight and I was in Zone 1, however upon boarding, several other zones went in ahead of me, leaving no overhead cabin space near my seat. This created a challenging disembarkment process.

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

It was a no frills flight. Would have liked to be able to charge my device

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen

Everything went as planned. Crew was great. Seats were still not that comfortable.
