Overall good. Plenty of legroom and fairly comfortable seats. No issues with capacity and the overhead been even though most people brought several carry-ons on. I don’t think Breeze really enforces the pay for a carry-on rule.

Overall good. Plenty of legroom and fairly comfortable seats. No issues with capacity and the overhead been even though most people brought several carry-ons on. I don’t think Breeze really enforces the pay for a carry-on rule.

Surprised at how much I enjoyed Breeze. Paid for the Nicer upgrade which made it closer in price to a flag ship carrier but with more comfortable seats and much more leg room. Crew was polite and since we brought our food no loss there. Would make the point that the ‘have to pay for a carry-on is BS’. Most people did not and had several. Still was plenty of room in the overheads.

Comfortable seating, adequate space available, nice to have USB port, polite crew.

My experience is typically great with Breeze. This trip wasn’t any different.

This was my first experience with Breeze. The plane was cleaner and more comfortable than any other I've experienced. The process of boarding was streamlined. We boarded early and arrived at our destination 45 minutes early. The only hiccup was my ticket was rejected by TSA PreCheck and I got sent to the back of a very long line at Fort Myers. I entered my information when I bought my ticket, but it apparently didn't connect to my permanent profile. I'll correct that for next time. I was expecting an Allegiant experience, but Breeze was much more upscale. I really, really enjoyed it.

Great experience. Non stop is great in and of itself.

Lady at check in counter helped me get a seat in the cut row all to myself.

It was great except the other passengers who didnt have children complaining and not giving grace to the mommas with tiny babies who were trying to comfort their little ones during the decent. They were clearly trying and every child travels different.

It was pretty good. Only thing that makes our boarding uncomfortable was, that we had to pass TSA at terminal 1 and after that walk 15 minutes to terminal B, because bus was insufficient to take so many people and waiting time for the bus was more then 1 hour.

Something about the chair was uncomfortable, Maine the curvature of the back.

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service
