Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

Great vacation. Can't wait till next year for another one.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.

Our flight when we finally got rerouted to a different destination than we were going was fine. But 2 days was taken out of our vacation because our flit was cancelled. We understand mechanical problems and of course don’t want to be on a plane that has mechanical problems.Wish there had been another solution.

Kayak wouldn’t refund me for a flight I was trying to cancel through Kayak. Alaska airlines said I had to cancel through Kayak. I called the customer service line and they couldn’t refund the flight that I booked through Kayak either. You stole my money. You will be hearing from my lawyer.

The bathroom trash container under the sink fell out and was like that long before my flight. The plane smelled of canned fish and floor was Deteriorating

I behave had better flights this one was old and poor

Great airline attendants. However I could not get the entertainment to work on the app

See previous. It was the flight from Honolulu to Kapalua that was cancelled.

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

Good. Flight was good. Crew was good. Wish they offered coffee refills. Wish I didn’t have to pay for headphones. Otherwise good for a commercial flight.

Should have been forthcoming for reason for delay. Should have been able to check in for seat I'd like.

It was fine. It was a 30 minute flight so there was water or fruit juice and no food. Which was totally fine. The check in, gate and flight crew were all excellent.

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Loved flying First Class. Very comfortable. The seat was amazing. Enjoyed a movie and was able to relax so much better than in coach.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Delayed, toilets did not flush, pilot parked to far away from Gate

I like flying first class, and United has a nice one

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Older aircraft, no meal, only food was for purchase. Not impressed United.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

Check in was rough because the check in crew did not know how to manage my international visa documents. Required a long process and 4 people to finally be able to proceed to security. They told us incorrect information several times before acknowledging we did indeed have everything we needed from the start.

Poor communication ahead of time about flight delays and old planes/other equipment.

Mechanical issue delayed us 2hrs and then once we landed sat on tarmac for 30mins because someone left a vehicle in front of the gaye

The crew was excellent and overall the flight was good. No complaints.

Like all of the flights I took to get down to Dallas. They were delayed

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

Flight pulled out on time but sat on runway for 30 mins. It was extremely cold in the aircraft despite wearing a winter coat. Surprisingly they had a vegetarian meal but could have some better snack choices for a 8 hour flight.

We had a male flight attendant who was super attentive and wonderful! Very professional. I have both gluten and dairy intolerance, and was only able to get a gluten free part, and not the dairy free part of the meal. Easy to order ahead of time and I appreciate being able to do that.

It was a train wreck but on an airplane. First off, flight was delayed then we board only to hear two announcements, First weather delays in Orlando and second backup battery warning on emergency lights. After sitting on the plane for almost 2 hours they have us deplane due to the maintenance issue. We were told they were getting another plane. In the mean time, I notice another American- Orlando flight and ask the gate agent if I can switch. He says he cant help me and I'd have to walk to A13 from A37. Really!? I get down there and get a seat only to get an announcement my original flight was RE-boarding. The Then inflight there's no communication and I notice on flightaware were circling over the Gulf of America. I call the flight attendant and of course she has no clue and apparently 5m later the pilot finally tells us about another delay. Why does American always have these service and delay issues? They are my LAST choice in flights now!
