Airline reviews

Pros: "Boarding was a fast and smooth process. Flight attendants were there to help with carry on luggage if needed. Always nice and do their best."

Pros: "The gate crew were very responsive and told us accurate estimates about the delayed departure time. They even distributed snacks for us."
Cons: "The flight crew was subpar. We had been delayed by 2 hours and they did nothing to assuage anyone’s frustrations. Service was minimal and lacklustre. In flight WiFi didn’t work with any streaming service. Plane was noisy and old. Seat was about worn through. Truly the worst in flight experience I can remember having domestically."

Pros: "I reached y destination."
Cons: "One flight attendant yelled at me for switching seats, even though I had asked permission to move seats. Another flight attendant clumsily kicked me when leaning over to serve another passenger. After living in Japan, it's pretty rough to see the low bar of American customer service."

Cons: "You shouldn't schedule a flight for a plane that is due to have scheduled maintenance. It's not like this should come as a surprise to you. Also, there was at least one over-served passenger on board who became loud and obnoxious, shouting obscenities."

Pros: "Fast on the plane"
Cons: "Getting off the plane quicker"

Pros: "All was great"
Cons: "Nothing"

Cons: "Hour late and no wifi!"

Cons: "Seem that they turned off the air conditioning once we landed in the cabin got on the warm side."

Pros: "Quick flight"
Cons: "Coffee or beverage service would have been a nice touch."

Cons: "Passengers should have the option to ask for additional snacks."

Cons: "I’m tired of Delta gate agents “requiring” those in Main cabin 3 gate checking bags!! Both legs of the trip it came to a point they said it’s mandatory to gate check all remaining bags. We get on board and there’s plenty of overhead space. Even a flight attendant mentioned how empty the bins were!"

Pros: "Smooth ride"

Cons: "Couldn’t hear boarding announcements. Lots of boarding confusion"

Pros: "Helpful"
Cons: "More print media to read on"

Pros: "The service on plane was great and so was the opportunity to check luggage, although I was happy I didn't have to."
Cons: "Boarding from DTW to LAX, we had to stand for a long time on the jetway and it was really cold. It was the holding place after they checked my ticket. Otherwise, it was a great experience flying Delta."

Pros: "Flight was very late- about 45 minutes because of some problem with the "paperwork" they said. It was a beautiful day and the crew was ready to go, but we all sat for a long time before being allowed to leave Madison. It's especially bad when we've all made ourselves arrive at 5am for a 6am flight"
Cons: "on time departure"

Cons: "My kids were asleep when the flight attendant passed the snacks . I asked to get the snack for them and she told me they will have to get it in the back of plane once awake. Didn’t argue but was surprised"

Pros: "New plane. Great movie selection. More stylish seats + bathroom. Overall very good and I think Delta has really made an effort to improve it's service. It's noticeable."
Cons: "Plane felt very dry compared to others. The electrical plug outlet jams right at around your knee level. Bread was cold and rock hard (seriously, can we not come up with a good solution for this?)."

Pros: "Great service from boarding to landing"

Pros: "Delta is always fabulous! Their crew is so helpful!"

Cons: "delayed flight"

Pros: "We had purchased economy tickets and got assigned seats that were not next to each other. As we were boarding the ticket person gave us a new seat assignment closer to the front and next to each other – we really appreciated and liked it. Makes me want to fly Delta again!"

Pros: "The flight itself was fine, boarded on time and arrived on time."
Cons: "A pet peeve of mine is having to check my carry on. They said the overhead bins were all completely full, so I checked my bag at the gate. Come to find out, there were a few spaces left and it wasn't necessary. Really annoying."

Cons: "Need vegetarian meal in first class"

Pros: "Everything went as planned!"

Pros: "The nice staff and entertainment options."
Cons: "I usually fly delta and have a great experience - unfortunately my flight from Detroit to Seattle was not. To start off, i was flying with two other people and we were not able to get seats together, and the whole seating process with delta is really difficult even when I had called weeks in advance to see if they could try and seat us together. I understand with main cabin tickets you can only choose your seat as you check in, but it would be nice to be able to request seating with a person/group you are flying with. I was placed in the very back row of a busy flight, and noticed that the horrible smell from the bathrooms which made it unpleasant. As said above, I normally have a pleasant experience.. but being a delta sky member I feel as though i do not really receive any differences as to a non-member. I hope this review helps for the next customers! Thank you."

Cons: "On time, free upgrade."

Pros: "Seat was upgraded."

Pros: "The crew and overhead storage."

Cons: "Seats are so tight so uncomfortable"

Cons: "3.5 hours late."

Pros: "Got me where I needed to go at the price I wanted to pay. - The gals at the ticketing desk were extremely helpful and cheerful."
Cons: "Not my typical Delta experience: -Boarding for special needs was a joke. A literal ‘run-on-sentence’. No more did I get up and they went to the next group. I was almost knocked over in the rush. -The onboard staff was nice enough. However, between the two of them, one of them had a thick accent. Maybe that one shouldn’t be the one making all on board announcements… and please fix the horrendous crackles too!!! -It seemed our pilot was in training… during our short flight a series of right and left turns were made, no effort to avoid turbulence, and the landing was surprisingly hard. It felt as if my spine took a quick jab to my brain as a result! What’s up?"

Pros: "Leo was friendly and helpful, a wonderful presence on the flight."

Cons: "I paid extra to sit comfortably only to have the seat adjoining my occupied by someone who expanded over onto my seat! Leaving me barely any room to sit comfortably."

Pros: "The Delta people were solicitous, efficient and brilliant the whole way through. We had not a bit of trouble. Our first class seats were comfortable, but with the supplied blanket, pillow and poor air conditioning it was a hot flight. The cabin personnel were wonderful as per usual, and my tasty gin and tonic soothed any discontent. I wish I could fly this way all the time!"
Cons: "The private contractor handling wheelchair assistance was terrible. A Delta employee theorized that they do not pay enough to attract and retain personnel. Our pre-arranged chair was not there, multiple calls by our Delta assistant finally got us a ride to the chair holding area, but after about 45 minutes we gave up and shuffled off to the security area on foot. Thank goodness my hubby is mobile enough for that to have been an option. When we abandoned our wait we were still 4th in line for an attendant to push the chair. If Delta has any responsibility in this it would be in the retention and compensation for the private contractor."

Pros: "The lights where off to make it feel more homie, I liked that I had the seat to myself and the crew was nice."

Pros: "Premium boarding breakfast sandwich pretty good"
Cons: "My screen stopped working in the middle of an episode."

Pros: "Empty seat next to me and actually got to stow my bag overhead. Good entertainment options. On-time departure and arrival."
Cons: "Wi-Fi not functioning for second flight in a row. No food available for purchase, not even snack boxes. Best I could get was three bags of almonds."

Pros: "Free movies helped the time fly by. Stewardess, or whatever the PC word us now, Britt was awesome"

Pros: "Entertainment"
Cons: "Late flight without any compensation for our trouble"

Cons: "Wifi didn't work (network wouldn't show up)."

Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."

Pros: "I always feel that the flight attendants on Delta truly care about your flight experience. The smile, the attentiveness, the thoroughness and giving you the attention you desire."
Cons: "Ran out of bananas before they got to me, no big deal and it looks like Delta is getting healthier options every year."

Pros: "Cheap"
Cons: "My roundtrip flights with delta were all delayed at least 2 hours. That's what you pay for for a cheap flight. There were no inclement weather and the staff didn't give a reason for the delay."

Pros: "The crew was very accommodating and helpful and the new entertainment systems with the free movies are awesome. Because of the heat in the cabin we received additional beverage service and follow up waters"
Cons: "The air above my seat wasn't working for the duration of the flight and there were problems with the air throughout the cabin so it was uncomfortably warm for the whole flight."

Pros: "Got lucky, and got an upgrade!"
Cons: "Good staff on the plane very sweet like. Actually arrived early. Thought we would get breakfast on the flight from Madison Wisconsin to New York City."

Pros: "the majority of delta flights i've taken over the past few years have had huge issues - either long delays or cancellations. i won't be flying Delta again"

Cons: "This flight was on a Transavia codeshare with Delta and a real downer after coming from a Delta One business class segment. An uncontrolled mass boarding, crammed in seating, no amenities and charges for a drink of water made this a pretty crappy flight. The crew was nice though."

Pros: "The crew was friendly and willing to serve."
Cons: "Seat could have been more comfortable (it is thin) and more space/pitch between the rows of seats."

Pros: "The crew was Ok except at the beginning when they could help more inside the plane with finding the seating."
Cons: "I missed the plane shopping because i don’t recall seeing the crew after the meal offering it. I heard the announcement at the beginning of the flight so I was looking forward to make purchases. Later when I asked it was already closed."

Pros: "Comfort of A380 Legs space"
Cons: "Terrible Connecto in Frankfurt We had to run for 15mn to get our Singapore flight with no help from Lufthansa: poor service"

Pros: "Nothing"
Cons: "Lufthansa is not a pioneer flying company as you think, everything comes from Germany is low quality especially service!!!"

Pros: "Crew was the best ever."
Cons: "Space is always an issue on super Kong flights, so any improvement for these 11 hour flights would be great. A place to stretch somewhere?"

Pros: "everything from the boarding and check-in process to in flight comfort."

Pros: "The crew."
Cons: "The airplane arrived over 45 minutes late."

Pros: "The crew was nice and the movie selection was decent. Food was ok. As good as it can be when you pay $2,500 for a flight ticket knowing that they are not really there to offer you a service, they are there to make their own money knowing that as a traveler you really have no options other than an airplane if you want to go across the ocean."
Cons: "The difference here is that in a 9 hour flight you want to keep hydrated. Crew seemed lazy...they would not bring water to travelers very often...and when I called a flight attendant with the button call and politely asked if I could have some water, she seemed pretty annoyed and told me I can just stand up and go take my water in the back where they store food. NOT A GOOD SERVICE FOR $2,500!!!! It’s outrageous!! Seats become smaller and smaller...and you keep asking about my experience...$2,500 to travel seating in a miniature seat with no leg room is a bit much...and I know no flight company cares about this...we have no choice...either take that or don’t travel, right?"

Pros: "Overall, a good flight, slightly earlier than schedule, well informed by the pilot"
Cons: "The food was not up to par for Lufthansa (plane food). The choice was barbecue chicken or vegetarian pizza. I asked for vegetarian pizza. Not sure what I had, as it did not taste like BBQ chicken, and it did not look like the food my neighbor had (which looked like 2 mini pizzas). I chose not to complain about my food. It appeared passengers were keeping the cabin crew very busy. By taste, I could not tell what it was and I could only eat half. Not usual for Lufthansa food."

Pros: "Great service. Comfortable business class seats."

Pros: "Great crew!"
Cons: "The sound quality of the loud speakers for the announcement was awful. The sound for the movies was also not great."

Cons: "It took ages to go through the security check, although I have mentioned that I have a flight connection that is due to leave nobody gave a s..t, so I missed my flight. Now I’m waiting at the airport"

Pros: "Overall it was a good flight."
Cons: "The dessert could have been better than a Kit Kat chocolate bar."

Pros: "On time, no complaints"

Pros: "One of the crew members, a male, was very nice."
Cons: "•We boarded and consequently landed late, which caused my cousin to miss his connecting flight, coupled with the long customs process upon landing. There was no accommodation given to my cousin so I have to take him back home with me and then drive 2 hours tomorrow morning to bring him back for his new flight. •The charger ports for our seats were not working, which means we were 8 hours + without a phone. •One female flight attendant had a bad attitude and dropped pretzels in my lap after I turned to quickly ask my cousin a question regarding what drink he wanted. •The plane landing was one of the most reckless I’d ever witnessed."

Pros: "Friendly crew. Flight left on time"

Pros: "At least Lufthansa has a little bit more leg room."

Pros: "Wonderful crew and amazing soft landing, like cream."

Cons: "Flight was delayed. Neither United app nor in flight entertainment worked. Boarded way too early, then sat on the plane for over an hour."

Pros: "The seats and leg room were spacious enough. I liked the many options of movies."
Cons: "The vegetarian option was gone for the second meal. The touch screen TV was not working properly. Had to push the buttons multiple times"

Pros: "Great movie options, relatively good food for an airplane."
Cons: "Booked way in advanced, paid extra to book upper deck on both; outgoing flight Miami - Frankfurt and return, but was bumped out of our seats. Spent 2 hours on the phone trying to book them again, and ended up on a lower deck on the Miami - Frankfurt flight, but re-booked on the upper deck on Frankfurt- Miami flight although not the side seats as I originally booked myself, but in the middle section. The entertainment's touch screen system is inadequate, not reacting to touch efficiently."

Cons: "Will newer agan fly business with Lufthansa!! It's not business at all just regular econom seats with short leg room and casual service. They should be sorry for that kind of business!!"

Pros: "We had a very kind crew! We traveled with an infant and while boarding was a mess, the crew on board was kind and helpful and did all they could to make it a good experience."
Cons: "Air Canada Rouge operated our flight rather than Lufthansa or other similar airline. This meant that there were no tvs on board, which means the nearly 9 hour flight got very long. Boarding and check-in were also disorganized and many people from lower zones boarded before zone 1 and those with children, m among we had to stand on the ramp for a very long time holding ort baby."

Pros: "People of Lufthansa and the clients who were flying with me."

Cons: "My plane was non existent and put me on a time crunch for connecting flight."

Pros: "we flew United"

Cons: "The seat was getting pushed back"

Pros: "Exceptional staff, service."

Pros: "You disappointed me"
Cons: "Noting"

Cons: "Delay in boarding, delay in removing snow/ice, my seat was changed without notifying me (after i checked in on line the day before)"

Cons: "Missed connection along with about 25 others due to the delay getting to Lisbon (no reasons given)."

Pros: "Shortness of flight from Genoa to Munich"
Cons: "Layover following"

Cons: "No boarding lines. Boarded late. I was not given enough time from my arriving flight. I had to spring the length of the airport and up and down stairs as the elevators had long lines. Maybe it was good it boarded late or I wouldn't have made it."

Pros: "Smooth flight, good service"
Cons: "Leg room."

Cons: "2 1/2 hour wait while boarded then missed flights in toronto. Toronto airport a mess! Unclear directions and procedues."

Cons: "The flight attendants that provided service in my row where not very friendly and at times rude."

Pros: "Very nice and caring crew."

Pros: "Lots of great choices in movies and music; good food; great service"

Cons: "The fact that the person in front of us could push her seat back to the point that the TV screen was up in my mother's face. Just because someone has paid extra for a better seat, does not mean they should inconvenience elderly people (who are less flexible in moving further back). This creates a poor environment. Please consider not having your seats recline to the point where they make the person in the seat behind, extremely uncomfortable."

Pros: "Pre-bording with children and nice entertainment selection of movies, tv shows and music."
Cons: "rhe FA was saying that they have either pasta or chicken and they had beef, when asked what kind of pasta he said how would I know."

Pros: "Boarding was quick, staff was kind and helpful."
Cons: "N/A"

Pros: "I appreciate the taxi, in Munich airport, to my next connection."
Cons: "I disliked the late departure."

Cons: "Nothing"

Pros: "Good flight good staff. Captain explained the route which is nice."
Cons: "No negatives"

Pros: "food remarkably good decent entertainment comfortable temperature on time, not waiting everything went as expected."
Cons: "sadly, airplane seats just aren't that comfortable. But that is universal and expected."

Cons: "coach seating sold as biz class"

Pros: "The plane stewardesses were actually really efficient (German style). Because of being on the waiting list to get on the plane I couldn't get a seat next to my partner so they did the biggest math exercise to put us together. Props to them"
Cons: "The flight overbooked (I still don't understand this concept, since is basically selling twice the same seat, right? Is that even legal?) Also the system was down, so no check-in online = the biggest line at the airport, it took me more than 1 hour to check-in and drop my luggage, all to get there and the ground force lady (the rudest person alive) tell me that I had no seat available, that she was going to put me on the waiting list... WHAT? I bought my ticket already, waiting list? Well, to say that I highly doubt that I'll book with Lufthansa again."

Pros: "Crew was fine. Food was ok."
Cons: "Delay, twice - before we boarded and then again after we taxied."

Pros: "The flight was very good."

Pros: "The stewards were very prompt and polite. The food and wine were good"

Pros: "Friendly crew in business class."

Pros: "Not a thing"
Cons: "The fact I didn't even make it to my destination. Not one person working for Air Canada gave me the impression they knew what was going on. They certainly didn't apologize for ruining my vacation and they did not try to do a single thing to help us make our flight or make the disappointment of missing it any better."

Pros: "Overnight flight so slept. Flight attendants were friendly and helpful."
Cons: "Cramped seating. No entertainment."

Pros: "The seat space was good and the flight ended without incident."
Cons: "The flight was delayed which happens, but there was no communication as to why or how long it would be or any other information. In flight the crew were barely visible as I had to ask for refreshments and then they brought it around for everyone. Next was cleanup which took way longer before it showed up."

Pros: "Flight was confortable and crew was great we even arrived slightly early."
Cons: "One of the onboard meals was literally cup noodles with sides."

Cons: "- flight departed late but been told there would be no problem catching short connection - connection plane was there and still connected - could not board : tickets were cancelled while we were in the air in previous flight! - next flight left actually ... 1 min early. We could have boarded - been told it was because of luggages that could not connect. Lie. - clear case of over booking - disguised so Air Canada wouldn't pay for it"

Pros: "Friendly attendants, excellent foods"

Pros: "Plenty of space. Attentive crew. Food was acceptable."
Cons: "Nothing"

Cons: "There was a horrid family in the row in frony of me that absolutley refused to control their child at all, even when airline staff stepped in , so a really long flight was made to seem even longer and sleeping was out of the question."

Pros: "Entertainment unit and comfort were standard 5/5 for both"
Cons: "Boarding a massive 777 is difficult but some how other airlines do it smoother. Not sure how boarding 3 zones at once makes sense, which created a long que. Plus a delayed plane didn’t help the matter Unnecessary comments by one crew member while passengers were putting away their luggage were over heard and provided no value to the situations. Cup of noodles and a 3 tiny pieces of beef plate were provided for dinner which was very disappointing. While a typical egg breakfast and snack were also provided. Hot beverages were generally not served due to turbulence and water service during the 12hr flight was minimal."

Cons: "delayed by 5 hours"

Pros: "Cancelled my original flight plus 2 hour delay. Crew not exactly nice either."

Pros: "Cheap tickets at short notice."
Cons: "Inability to check in online and via machine in transit. Cheap flight gets you cheap service. My entertainment console did not work and had to ask crew to reboot it. Many others had same problem. Food is below meh. My travel was Air Canada all the way but portions provided/partnered with Alaska Air. I was not able to check in for both portions of my travel from HKG to YVR to SEA."

Pros: "Price"
Cons: "Power outlet's didn't work"

Pros: "Smaller airport with quick checkin and pleasant staff."
Cons: "No entertainment system and have to pay to access in flight wifi to access a movie."

Cons: "same as above"

Pros: "Great service, multiple meal/snack services and staff was friendly and helpful when needed,"
Cons: "The customer service line through telephone was not very helpful and seemed to cause more worry when we ran into a problem with our flight."

Pros: "This was not a Luftansa flight!! It was Air Canada Rouge which is a budget airline that doesnt compare to Luftansa"
Cons: "The fact that it said thia was a luftansa flight when in fact it qas not"

Cons: "2 hour delay, lack of connecting ticket made me have to go through security all over again, the "entertainment" is an app for your smartphone/tablet."

Cons: "Our flight was delayed by 3 hours. The delay was announced after we had boarded and sat in the plane. Not acceptable. For the delay all that was served was water after about an hour, and pretzels and soft drink after two hours. Not acceptable."

Pros: "Once I made my flight (the next day) everything went smoothly"
Cons: "Online checkin does not inform passenger if their passport is suitable for travel. Although my online checkin was successful, once at the airport the attendant would not allow boarding because expiration was within 6 months of travel - a requirement for certain countries. It would be much more efficient - for airline and passengers - if the online check in system can catch this before arrival at the airport."

Pros: "The food was pretty good!"
Cons: "*The in-flight entertainement required you tonise your own mobile devices, but locks "premium" content (movies) and forces you to install an app to view it - which you can't do once your on the plane and have no wifi. Also, there's no way my iPad would've lasted 7h without a charging port anyways..."

Cons: "Flight cancelled on Monday due to runway repairs. Rebooked on Wednesday. I could walk faster."

Pros: "Friendly service is so important to me - and the staff and flight crew at Air Canada met all my expectations. I had the displeasure of flying United on the way to Seattle and I must say the service at Air Canada is far above!"

Cons: "Flight was delayed by roughly 2 hours allegedly due to construction at the Toronto Pearson airport. I recognize that this was possibly not Air Canada's fault but the delay was still unforeseen."

Pros: "The most outstanding part of the trip was the Check-In Agent. My original flight was cancelled and the very lovely lady at Check-In was so nice, very professional and just gr at to work with. On the whole AC is just, well, better than average and a great outlook on the people perspective."

Pros: "The crew was friendly and Air Canada staff was great. The food was okay but not as impressive as other international flights we've taken."

Pros: "Crew was very helpful and nice, plane was new and in a very good condition. Flight was not fully booked so we could move around and take even 4 seats to lay down and fly comfortably."
Cons: "Boarding was over an hour later than it supposed to be. Toronto always has some " surprises" for passengers. Food could be better."

Pros: "Air Canada you suck. Told us that our flight wouldn't leave before we boarded as the computer system was down country wide. We still stood in like for an hour and hey could have manually checked us in as they did others. We were promised no planes would leave and when we got to the gate our plane was pulling away leaving 10 of us to scramble to find another flight. Customer service argued with me saying no flights were going to Ottawa and my Kayak app told me otherwise. Thanks for making my flight home for a funeral that much more stressful and having my family wait 4 hours risking all of our lives with freezing rain drive home."

Pros: "Great price, easy transitions and connecting flights. No complaints here!"

Pros: "Nothing!"
Cons: "Flight canceled due to mechanical problems. Out of 4 agents at desk at airport only one knew what to do in case of a cancellation. They all stood around eating raisinettes! Unprofessional, lack of training, lack of planning (why wasn't another plane sent). One agent was going through the line giving out a phone number to call? Why weren't they trained? I called and thankful I was up at the desk so I could tell the agent what to do from the lady on the phone! Lost a day on our already short Christmas visit with family. Would love a refund!"

Pros: "Check in agent let us check out carry on without a fee. (Plane was fully booked)"
Cons: "Air waitress wouldn't let me use the front bathroom even though the back one was blocked by the beverage cart. Flight attendants didn't answer my call button when it was on for over 20 minutes. Yes I turned it off and on again. When she finally came by she just turned it off and walked away. Just wanted a glass of water. Initially didn't serve a glass with my bottle of wine."

Pros: "Nothing."

Pros: "Staff was courteous and tried to get people with large luggage to check it."
Cons: "It took forever to load as people carried on huge bags that wouldn't fit in the overhead bins or under the seats. It took an extremely long time to get through American customs, and they were very rude, not caring if people missed connecting flights. They wouldn't add workers. Some almost missed the flight. P"

Pros: "Nothing"
Cons: "Everything"

Cons: "Small legroom and poor selection in the entertainment provided via wifi"

Cons: "Horrible to say the least"

Pros: "Nothing"
Cons: "Never flying Air Canada again!!!!"

Cons: "5 hours late with no info"

Pros: "Everything was great."
Cons: "Movies were way too old and too little selection. If one does not have a mobile device has to pay for entertainment."

Pros: "Curtous and competent crew. Good Price Direct Flight"
Cons: "Very little perks on the flight. Flight right at dinner time and no food provided (Need to be purchased on-board. Not all choices were available). Entertainment system required to provide our own devices, but it was not possible to plug in to recharge (5 hour flight!)."

Pros: "Food"
Cons: "Mechanical problems and missed flight to Milan. Then next day flight to Milan delayed. Air canada put us up in cheep hotel with minimal food vouchers."

Cons: "You"

Pros: "Great food and great service. Not much leg room in the 'free' seats but the flight crew allowed us to move to an empty row so we had lots of room. Would definitely fly with them again."

Pros: "I upgraded to premium economy which made a big difference. Lots of leg room, a menu, pre flight drinks."
Cons: "Airline lost my luggage."

Pros: "The food was very good, and the alcohol was free even the second time around which i liked"

Pros: "Arrival and departure on time."
Cons: "Prefered seating promised more leg room. However I paid 63 dollar extra for same type of economy seat. Long lines to drop bags at airport, even after checking online, paying for bags, and printing bag tags. Check in seemed disorganized. I had TSA prechecked on arrival, but still needed to wait in very long lines upon departure."

Pros: "Comfortable seats, great complimentary entertainment."

Pros: "Flights were on time and the crew was friendly. Each seat had its own TV with many movies. I liked that the on board menu for food had many options including buying a first class meal."
Cons: "I wish they would give out even little cookies for free or something. Everything is pay for purchase."

Pros: "Things were very good. Staff was freindly."
Cons: "The internet wasn't working but not a problem for a 1 hour flight."

Cons: "This was a regional jet, and this flight segment was 3 hours. The seats seem to have a little more leg room than larger jets but much less cushioning, and the pitch/shape of the seat back was very uncomfortable. I could barely walk when we reached Houston."

Cons: "Very crowded plane."

Pros: "Emergency exit"
Cons: "Extra blankets as emergency exit is terribly cold Boarding"

Pros: "Good flight, decent crew. Food was okay."
Cons: "My entertainment set didn't work because the headphone jack was broken so that was a major bummer."

Pros: "Our flight attendant was the best!"
Cons: "The weather."

Pros: "The pilot tried to make up lost time in the air."
Cons: "Due to regulations, our crew had to delay our flight 39 min. This was done the night before. There was no way we were going to make our connecting flight, but no one from United seemed to care. The crew from milwaukee to Houston was rude and unhelpful."

Pros: "The food was very good. The crew was very pleasant and accommodating. A bit late leaving but time was made up in flight. All in all a pleasant trip."
Cons: "Some of the entertainment screens were inoperative. The occupied light for the forward restroom (in business class) was not working so you never knew if it was free or not."
