Pros: "Early Arrival"

Pros: "Entertainment ststem"
Cons: "Heat: service; lack of water/drinks; lack of soap in bathroom"

Cons: "Our flight was delayed while we waited for a crew member to fly in to cover for a FA that called in sick. Gate agents didn’t provide many updates while we waited. The were only 3 snack items for purchase available on the plane. Seat didn’t recline"

Pros: "Partnership with Virgin. Drink orders."

Pros: "LOVE the Virgin planes and the ability to upgrade. The food and beverage options on the Virgin flights are amazing. PLEASE keep the format of these planes the same!"
Cons: "Nothing"

Pros: "Everything was easy and normal. I felt everyone was treated well."

Pros: "I arrived - finally (though stuck on the runway at SFO as I write this)"
Cons: "Crowded, chaotic boarding area & process at Boston Logan. Checked in seats manually since systems apparently down. An hour delayed (on takeoff) for no apparent reason and delayed waiting for gate on arrival. Seems to happen regularly with Alaska but not JetBlue Broken restroom - should have at the very least let coach customers use First Class restroom rather than get by with one Broken wifi - none the entire flight Limited food which ran out quickly Flight attendants trying but seem harried and confused and not very attentive"

Cons: "At boarding, when overhead bins are full, you cannot force passengers to check their bags if they had planned not to. I was in a rush when I land and because it was delayed too I did not want to also have to wait for my bag at baggage claim. I was completely late to an event I was to be at."

Pros: "Pleasant staff"

Cons: "Everything!!!"

Pros: "Team very nice and polite."
Cons: "All the airplanes should have screens"

Cons: "By the time I boarded I was unable to take my bag on as all overhead compartment space was gone. My bag was not prioritized, instead I had to wait FOREVER at SFO for the bag to arrive. There were over 6 flights assigned to the same baggage carousel. I think since we have to pay now for bags to be checked, I should have been compensated for NOT being able to take my bag onboard and for being forced to wait a very long time to retrieve it...exactly what I had hoped to avoid by carrying on."

Pros: "The extra seat next to me."
Cons: "The fact that my baggage got left in Portland."

Pros: "normal."
Cons: "."

Pros: "Free wine"

Cons: "the flight was 2 hours delayed but the staff continuously kept us up to date"

Cons: "It was a 6 hour flight and I didn’t know only 2 snacks and a water were available on the plane until I got to the airport. Almost everything was still closed at the airport. We were quite hungry and thirsty."

Pros: "It has been over 2 years and I still remember the service, comfort and atmosphere of this flight. Whatever JetBlue is doing, it works!"

Pros: "I liked the male flight attendants on my flight. They were nice and cheery and was always willing to help. The inflight entertainment and WiFi was great. The snacks were also good."
Cons: "I forgot to the flight attendant’s name but she was quite rude. I traveled with an infant who required warming up of her milk in a bottle and I would ask for hot water and she failed to bring it over. I requested hot water twice. Initially when the plane was taking off- she stated she cannot bring anything while the flight was taking off but even after take off and in cruising altitudes she did not come over until we rang the call bell and another flight attendant came over. Second time mid flight we happen to ask the same flight attendant for hot water as she passed by— she nodded her head but again never returned with the hot water. Again I hit the call button and another attendant came over and gave me water. I felt that she did not like attending to the flight guests and always seemed to give an attitude. I understand traveling with a child may be hard for others, but imagine the parents who have to care for a starving baby. The flight was also a bit too warm."

Pros: "Basic flight"
Cons: "Major delays. Poor updates on app regarding timeliness."

Pros: "Crew was very friendly and responsive"
Cons: "Would’ve been nice if they offer headphones. Maybe they did and I just didn’t notice."

Pros: "Very good service"
Cons: "More food choices"

Pros: "A 6+ hour flight is always tedious but jet Blue is always the best option, with live tv and a good supply of movies and snacks."
Cons: "Quicker departure, 20 minutes on the tarmac, but that’s not the airline fault...FAA Boston"

Pros: "Crew was nice and accommodating. Plenty of leg room in regular cabin. Good entertainment options.?"

Pros: "Great crew. Mint experience is fantastic, actually great airline food. Better than any other domestic first class. Free internet!"

Pros: "crew were great. free snacks with lots of variety. Great assortment of films available."

Pros: "Not too full of a flight"
Cons: "It was delayed 3 hours"

Pros: "Boarding process was smooth, and attendants were kind and entertainment system seemed good."
Cons: "Attendants could allow passengers to use extra leg room seats if they are empty once in the air. Would be great if the default setting for the screens was OFF."

Pros: "Crew was great. Snacks were abundant. R"
Cons: "Ran out of pineapple juice and giving out earplugs would be nice"

Pros: "Friendly crew. Extra snacks and drinks were a big plus on a long flight."
Cons: "There were not enough people that checked their carryons, which lead to a long delay in boarding. Jetblue people should have demanded more checked bags to avoid a long delay in boarding. The flight was painfully long due to snow, which is understandable."

Pros: "I like the comfort of the flight and the kindness of the crew"
Cons: "I'm disappointed that my carry-on has been charged like a suitcase, that has stolen time to reach my booked house in the city"

Pros: "It was really nice having a USB charger under every seat."
Cons: "Our flight was delayed by 2 hours and I was only notified when I had arrived at the airport."

Pros: "The crew are always nice and the plane clean."
Cons: "We always have a comfy aisle seat but it has happened on occasion by the time we are seated there is no room in the overhead not just for our luggage but people in our row. I would think an aisle seat is a premium seat. I think they allow people on with more than one carry on so people in other rows use our overhead bin."

Pros: "Competent staff"
Cons: "Rude TSA employee"

Pros: "In-flight entertainment was excellent: many options including in-flight wifi."
Cons: "I think it is time for US airline companies to provide complementary meals in their long flights. A 6 hours flight with just a small bag of chips? European airlines offer a complementary full meal even with a 2-hour flight..."

Pros: "Onboard staff was great"
Cons: "Boarded late, other flights planned on this trip one was canceled and the other was also late. Was told at boarding that bag checked at boarding would be at carousel at the end of flight, but it wasn't. Took forever to get a response and then the bag is still missing 2 days later and response has been terrible trying to sort it out."

Pros: "Seats were great. Excellent movie selection. Friendly flight crew."

Pros: "Comfortable seating, great movies, courteous service."

Pros: "Free WiFi, snacks and friendly staff"

Cons: "Nothing."

Cons: "2 hour delay. Too full and not enough over-head space for carry-ons, forcing some of us to check-in our carry-ons. Too many problems with the entertainment system (and downloading movies) for my seat and it resetting/initializing several times."

Cons: "Late take off and landing by 1 hour and sitting on tarmac forever upon arrival. JB used to be better"

Pros: "The flight attends did the best they could with information updates. They didn't know much more than we did."
Cons: "The catering issues delayed my flight almost 2 hours. Thank you to jetBlue for the email apology."

Cons: "Excellent flight attendants Clean, comfortable plane (other than the temperature)"

Pros: "Long flight so drinks and snacks were appreciated"
Cons: "The rude pushy passenger next to me who kept push8ng 8nto my space and stated that because I was on the Aisoe and he in the middle he should be able to push me 9verbbut that was not Jet Blue’s responsibility. Although the crew offered to move him to the back which he refused but it did quiet him temporarily."

Cons: "Late departure; headphone jack on my armrest was faulty so I had to hold the plug in the whole time if I wanted to hear sound of movies; once we were at the gate in SFO, it took a good 10 minutes for them to open the door to let us off."

Cons: "The Jet Blue counter person was not helpful at all providing direction to us from International Terminal to Domestic terminal C. No help at all to passengers who are not familiar with Logan Airport. Major major disappointment!"

Cons: "Had to check basic backpack at the last minute because no overhead space. Unclear instructions as to where to pick it up on the SFO end, leading to further delays getting out of the airport. (Already landing close to 2am at the beginning of a work week - minutes count.)"

Pros: "Felt safe and sanitary"

Pros: "Everything"

Pros: "The boarding was efficient"
Cons: "Three hour departure delay. No explanation given. No apology."

Cons: "My wife was told she could not board our flight from Boston to Paris because her passport was expired, even though it was not expired. We were told that in Europe passports cannot expire within 3 months of your departure. However, Delta never let us know about this rule until we literally were boarding the plane. How they could not make us aware of this until we were boarding the airplane is unbelievable and unacceptable. This has ruined our vacation which has been in planning for the last six months."

Cons: "the connection time between flights was NOT adequate especially considering I had to go through customs! AA did page me and had a representative (I think his name was Brian) waiting for me to help me get to my connection. He gave me a bright red/orange tag. I still hit some barriers. I was stopped in security and my carry on was put aside to be searched. It sat and sat . I explained to the man I had to go. He said he was working alone, so I had to wait. I was ready to leave it and just run to catch the flight, but the security man said I wasn't allowed to do that. He finally called someone else to search my bag (nothing found) I did make it...barely!"

Cons: "Too many delays as usual"

Pros: "Generally clean plane with good entertainment system and technology overall. Diabetic meal much better than in the past."

Cons: "The maple crisps were excellent from BOS to SFO. The pretzels were boring from SFO to BOS."

Cons: "Still in Houston after spending the night. Flight from Boston to SFO WAS DELAYED SEVERAL TIMES and we would have missed our connection to HNL. So we were diverted to IAH, where we spent the night and will leave for HNL soon."

Pros: "We like to have our carry-on available under the seat so I thought I was planning ahead by getting the second row. Turns out the front row puts their carry-on under their seat and the second row gets screwed. All my extra leg room was lost with my bag taking up the space because it could not fit under the seat. They shouldn't charge extra money for that seat and I felt cheated."
Cons: "No space for carry-on under seat in second row for upgraded leg room seat."

Cons: "Really expensive internet"

Pros: "For an extremely late gate arrival, United personnel were very accommodating."
Cons: "One flight attendant was more than curt and impatient when taking food orders. Cabin announcement told passengers to check menu in setback pocket. There was no menu. Attendant didn't offer one until another passenger who overheard conversation requested menu. As a frequent United traveler BOS > SFO, normally a 5-6 hour flight, attendants always seem to be rushing, brusque."

Cons: "The food selection. For someone like me who cannot eat cheese. there was absolutely no choice. Everything on the menu had cheese."

Pros: "Boarding was as expected, flight was on time, all was OK. Nothing to recommend particularly. d"
Cons: "Few choices in beverages and food. No decaf or green tea or coffee except instant coffee. "Snack" was nothing much."

Cons: "I told attendant my carry on had Med equipment. She proceeded to stow other larger carryons and tried to get me to check it — then she just put it in biz class. Cabin was hot. They brought me just after takeoff instas of at lunch time. My entertainment system didn’t work and the only response was “we’re aware of it” no attempt to fix, no apology. Then flight attendant skipped my tow with drinks."

Cons: "It was quite late"

Pros: "The first 10 minutes that I was able to access in-flight entertainment."
Cons: "After 10 minutes, the United WiFi was no longer available and passengers unable to acces in-flight entertainment. Passengers were also required to use their own devices. Monitors not available."

Cons: "the boarding process is horrible and feels rude. The design of the united gates is horrible, the long lines block others walking by. The lack of enough overhead space for carryon's is obnoxious. Overall very disappointing."

Cons: "Flight was super delayed scheduled to leave at 6:30 left at almost 9. Small updates with not much information. Entertainment system not functioning. Had to get a tow to the gate after landing??"

Pros: "Entertainment free and plenty of choices"
Cons: "Not even any free snacks, seats do not recline much at all"

Pros: "Staff was friendly"
Cons: "Wireless didn't work either way. Uncomfortable seats"

Cons: "WAs delayed for over 5 hours and missed my connecting flight. Had to abort takeoff go back to the gate and there were 2 issues with the plane"

Cons: "United sucks soooooo bad"

Pros: "I loved being in economy plus! The meal was a wonderful surprise and after my tv screen was reset, I enjoyed 2 movies. Nice staff and service."
Cons: "Having to go to the back of the plane for the bathroom."

Pros: "I liked that the air time was short and smooth (bos to sf)."
Cons: "We waited in security line for an hour. The plane was delayed for an hour for cleaning purposes. There was a plane at our gate when we landed. Ill avoid United for future flight purchases."

Pros: "Full flight, we got on smoothly and took off on time. The plane was clean and the pilots during abbouncekents were easy to understand and funny."
Cons: "I had to wait over 1.5 hours to use the bathroom because of the food and drink carts. The flight attendant would not let me use first clsss and told me I had to wait. That was way to long to make someone wait."

Cons: "I did not fly from Boston to SF on United. I did not fly to or from Boston. Please fix your algorithm"

Pros: "Not much. Staff were reasonably pleasant. Boarding process is horrible."
Cons: "United is still flying ancient 757s. Broken tray tables, lights no working in the lavatory. Treating people like cattle with the 1,2,3,4 lanes is unpleasant and demeaning. Everything is getting cheaper and cheaper."

Pros: "Crew was great. Very friendly and accommodating ."
Cons: "When we landed we waited 30 minutes to get to our gate. There was nowhere for the plane to disinbark."

Pros: "Crew was great"
Cons: "I've never had a good experience w in flight entertainment on united. Compared to other airlines it is simply a big step behind"

Pros: "We boarded very quickly. Take off and landing were immediate. I wasn't interrupted as I slept."
Cons: "The flight was delayed. Ordinarily, a little over an hour isn't bad, but we ended up landing at 1:30 in the morning, local time. I called United expressing concern about the arrival time when I was first notified of the delay and all I was told was "I'm sorry for the inconvenience." I learned later that there was an earlier flight I could have tried to get on."

Pros: "Boarding was easy, staff were okay."
Cons: "No entertainment, ran out of orange juice, cold and uncomfortable, old aircraft."

Pros: "Took off late but landed on time"
Cons: "Packed in like sardines. Hot on board."

Pros: "I didn't not make to my flight on time because I didn't know I need yo check in a day ahead but luckily there was another flight leaving over an hour and a staff was able change the flight for me without charging a fee. that was very nice. My seat was on three roll seats and there was another person was same roll and we share other seat and strength our legs."
Cons: "In flight movies did not work."

Cons: "1. Comfort: the headrest on these seats is so uncomfortable! It just props your head forward and causes a lot of neck strain. For most short haul flights, this is not a big deal, but it really makes for an unpleasant journey on the cross-country flights. Also, the four-seat middle section is so poorly designed. There is no way to store personal items under seats without invading the space of your neighbor because the metal frame supporting the row of seats doesn't match with the seats themselves. 2. Entertainment: United could not support continuous streaming of movies/TV shows for every passenger. My movie paused and froze so frequently that I gave up on finishing it and then felt like I had wasted my time. The speed and reliability reminded me of trying to watch movies on a dialup connection. It would be so much better to just have the TV screens built into the seats. All in all, United got a bad batch of planes and should try to take this into consideration when working with Boeing/Airbus on the next order."

Pros: "Flash for mac did not install"
Cons: "I felt like I was on my way to my death"

Pros: "It appeared as though I would miss my connecting flight and then crew moved me to an empty seat by the door so I could get off to make my flight!"
Cons: "The plane was too cold!"

Cons: "The last 5 times I have flown united I have either been cancelled or delayed to the point that I miss my connecting flight aND get to the destination. 24 hours later I will NEVER book a united flight again"

Cons: "Wifi not working"

Cons: "No announcement of the proper Boarding numbers"

Pros: "Flight was stuck on the ground for 2 hrs because of a generator issue, so I missed my connection. The United app nicely pre-booked me on the next flight to my destination without my having to do anything, which was cool. Internet didn't work but they refunded my purchase."
Cons: "The legroom is so much worse than jetBlue (which I usually fly) I almost couldn't believe it. Because of the generator issue the flight ended up being almost 9 hours. They ran out of ALL FOOD for purchase except chips (which they didn't even offer for free despite everything), so those of us in the back of the aircraft had our choice of a bag of chips for $4, or no food for 9 hours. Also, I paid $20 for the internet for the entire flight but it only worked for the first hour so I couldn't do any work."

Pros: "It was a comfy plane ride."
Cons: "I liked everything."

Pros: "Pleasant and attentive flight staff. Stewardess made a fresh pot of coffee and was back with a cup in less than five minutes. When a passenger got sick after take off the stewardesses handled the situation quickly and professionally."
Cons: "Nothing really"

Pros: "Boarding was consistent and timely"
Cons: "Older, worn interior, especially if seats are pushed back"

Pros: "The crew was pleasant, food-mini waffle was surprisingly good.not enough room between seats for tall people."
Cons: "Delayed on runway to me is no fun. I felt unsafe and like a sitting duck."

Pros: "Only outstanding thing about the flight was the agent, Annie C. who checked us in at Logan. She was pleasant, polite, friendly and so helpful. If only the other personnel at United were like her."

Pros: "On time boarding, nice crew."
Cons: "No free food, not a lot of options of free drinks"

Pros: "The flight was fast and the crew was nice."
Cons: "The boarding took forever"

Pros: "Attendants were friendly and helpful."
Cons: "One of the attendants was pushy and rude."

Pros: "Short taxing"
Cons: "Flight was delayed and the televisions onboard were not free"

Cons: "My seat cushion was not in correctly and very uncomfortable. Movies were free on my last flight and coat money on this one."

Pros: "We were bumped up to economy plus where there are outlets available. Outlets are nice. The entertainment options were very good."

Pros: "The airplane itself was great but the rest was not so good. United tries to sell you everything and the seating was miserable. We are back to JetBlue at first opportunity."
