Insights shared by verified travelers who flew the route from Boston to the United States 
GeraldFlew with DeltaBOS-SFOMar 2025
Book a flight early in the morning. The plane & crew will have arrived the previous night
HopeFlew with DeltaBOS-ATLMar 2025
Pack food unless you’re in first class. No food served.
ToruFlew with ANABOS-IADDec 2024
Delta usually has good equipment. Not luxual, but all convenient.
Verified travelerFlew with Alaska AirlinesBOS-SEAOct 2024
Flying Alaska Airlines from Boston to Seattle was an example of getting exactly what you expect. A no-frills basic experience, but one where the important things were accomplished, timely departure, on-time arrival, no drama, no glitches, completely as anticipated. I paid a little extra for one offered perk (seat selection), and I'm glad I did because my early morning flight was full. Next time, I'll likely pre-order a snack, since they looked good, were served promptly, and are priced right.
Verified travelerFlew with Alaska AirlinesBOS-SEASep 2024
I've always had my best luck with Delta and will stick with them in the future.
NicolettaFlew with Spirit AirlinesBOS-BWIOct 2024
Spirit airlines is climbing up the ladder! They're making a comeback! Smooth flight & brand new aircraft.

Check your departure time before go to the Aiport
GailFlew with JetBlueBOS-ORDJul 2024
Prepare for a long wait after you actually touch down. Ohare Airport is HUGE and you can taxi for a long time.
CarlaFlew with Alaska AirlinesBOS-SEAMay 2024
It’s a good choice. Seattle airport is huge and confusing if you are changing planes. Have plenty of time to switch.
KennyFlew with JetBlueBOS-LASApr 2024
JetBlue Airways has been operating very organized and flying with them couple times and they were doing very good job
Verified travelerFlew with Spirit AirlinesBOS-BWIMay 2024
That was my only flight, I selected it based on price and was pleasantly surprised with service.
BFlew with DeltaBOS-TPAMar 2024
Invest in TSA PREcheck. Quick and easy security check, with smaller waiting lines.
Verified travelerFlew with Alaska AirlinesBOS-PDXApr 2024
Non-stop Alaska Airlines flights are the best for this route.
GFlew with Alaska AirlinesBOS-SEAApr 2024
Would have liked to have more information on getting to my rental car off site It wasn't hard, but it would have taken less time and less wandering if it had been more clear
Verified travelerFlew with Alaska AirlinesBOS-SFOMar 2024
Long flight duration. Because of weather it took 8 hrs to get there . On my way back it was smooth and short
Verified travelerFlew with Alaska AirlinesBOS-SANMar 2024
Be prepared to wait in long line for shuttle to car rental complex.
NickFlew with American AirlinesBOS-CLTDec 2023
I'm happy with American. I don't travel enough on other domestic airlines. My experience with BA, Swiss, Emirates, and Lufthansa is obviously superior, but that's to be expected. I wouldn't expect that level of service and comfort from American. That said, my American miles go a long way and I've had a lot of decent low cost trips.
LynneFlew with DeltaBOS-MSPFeb 2024
The process was smooth and the staff were attentive; just leave yourself adequate time for security and use the Delta app - you'll feel confident that things will go smoothly in normal circumstances.
RobertFlew with American AirlinesBOS-CLTJan 2024
Be careful of short layovers because the airport in Charlotte can be quite busy and walk times can be long between gates
DavidFlew with Alaska AirlinesBOS-SEAFeb 2024
Not enough trips from Boston to Seattle to judge… flight times and boarding process were very positive.
SteveFlew with Hawaiian AirlinesBOS-HNLJan 2024
We used the Logan Shuttle from Woburn (we drove down from NH). Very good experience.
PatriciaFlew with American AirlinesBOS-CMHJan 2024
Not many choices. Only one non-stop per day so it’s usually full.
AdiFlew with Spirit AirlinesBOS-MIAJan 2024
Do not fly with Spirit. Boston agents are very very rude and unwilling to help.

Airline reviews

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.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

A bit rush for transit. Food and entertainment are not available

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

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

The gate attendant let me walk right by her with a bag too big for the overhead compartment

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.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Took off on time and successfully avoided weather that looked to be a problem along the way

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

Not having it be changed after we bought the flight tickets from a direct flight getting in at a reasonable time to a connecting flight red eye of 9 hours, so that we would lose our 35 dollars in nonrefundable insurance would've been great! Our country really does need low-cost carrier options, but this type of "service" ain't it. Fortunately, had a little better success with them flying to and from San Juan PR last month at least.

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

The only positive is that the flight made it both ways. Getting charged for every little thing after the cost of the ticket itself is comical, considering how the plane and services are as bottom-tier as possible. The self check-in kiosks are useless. It’s nice to think that you can print your boarding pass, tag your checked bag, and then just drop it off. But no, they still make you go through the line once you finish- what’s the point of the self check-in then? Any questions for the staff seem like the biggest inconvenience and were met with condescending responses. This was my first and now last time ever flying with Spirit. After all the extra costs, subpar plane and staff, I see no value. I’d rather drive the 13 hours than give Spirit another dime.

The flight was fine however what started as a reasonable priced ticket could have become an overpriced ticket with additional charge for carry on as well as checked bag $79 per bag per person each way. Additional charge for choosing one’s seat, additional charge for beverage and snack, we were on what was described as a new plane yet there were no audio/visual on the jet. A bare bones service but not at a bare bones price. Will think twice before flying Spirit again. 😕

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

I love Spirit. New aircraft, great cabin service, the airfares are low cost which helps me visit my hospitalized daughter anytime I can without paying a fortune.

Flight was 2hours late they had no crew or the pilot.

I paid for streaming wifi and the connection was poor.
