I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Everything would be much better if Kayak stopped nosing into my business with Delta.

Everything was smooth and easy to fly. No complains and a lot of thanks!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

When we enter the airplane there were many water drops falling from the ceiling all the way long to the seat , and when it departs were even more over us getting the hair wet , and later on was too hot , the A/C not work well.

The Comfort+ seats were well worth the upgrade, with the spacious seats and two checked bags! I’ll consider traveling this way or business class in future.

Pros: "Seating is better than most other airlines. In seat entertainment option, bring headphones. Accommodating crew. Beverage and snacks provided at no cost."
Cons: "It was the most mediocre flight I've taken in a long time. And I still had to pay $100 for an exit row instead of a regular seat. Really? $100 for no recline, no underseat storage, and nothing more than cliff bars and goldfish crackers? Delta.... You can do way better"

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

No in flight entertainment, gate employees were very quick and impatient, plane was uncomfortable

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

Excellent as always. Had issues checking-in online. Please fix.

Paid WiFi was only available for a few minutes. Avoid at all costs.

The flight attendant handled a situation in which an angry passenger was demanding to use his own supplemental oxygen equipment firmly but graciously.

The trip was very smooth. Flight crew were very friendly and efficient.

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

Seat comfort is still an issue. Seats way too hard or lacking lumbar support. Entertainment system has lots of nice features like “Don’t wake me for meals”. The Bluetooth headphone pairing works well if you know how to make your pods available for pairing. While this trip I didn’t find any of the many many movies that interesting, there is plenty in there for all tastes. Crew were excellent. Captain was good about telling us how limg seat belt sign would be on while going around a storm system. Wi-Fi was quite good for only $8 bucks for mileage plus members. Be sure to load a credit card into your United app to pay for food or drinks.

Late start, late arrival and very uncomfortable seating. If they schedule a takeoff at a specific time, how can they not know the traffic at the airport will be heavy and delay flights at that time? I paid for legroom but when seated next to an oversized person, I had no elbow room. Also, who wants to rub hips with a large stranger for over 2 hours? I ended up leaning toward the aisle the entire flight and being bumped every time someone passed by. Paying for legroom should include side-to-side space, too. This happened on both domestic flights I had within the past 2 weeks.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

Seats in coach aren't padded enough for a 6 hour flight

The absolute worst. Our flight from Madrid to Charlotte was delayed nearly 2hrs which cost us to miss our connecting flight. The only availability was to either separate my party of four (two being children) several other locations to reach our final destination. The other was drop us off at entirely different location we never intended on going. Thus resulting in us driving a rental 2 hrs to our original final destination. On top of that the flight from Madrid was uncomfortable and some staff were extremely rude.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Les 2 vols se sont bien passés, le temps de correspondance juste mais nous sommes arrivés à temps.

There was a situation before take off with a passager but the flight crew and others handled it very well. The flight attendants were great!

On time flight , great service from crew , comfortable and enjoyable

Boarding process was very similar to frontier or spirit. Gate agent measuring bags and denying boarding/checking bags.

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

Flight was delayed by well over an hour. Communication was terrible.

I like the team but I don't like the food you provided with money. I want free food and free water.

An average flight experience. For our transatlantic portion, they provided a main meal and two snacks. However, the food was not very tasty and the drinks far too small and infrequent for such a long flight. The regrettable part of the flight was that the toilets were extremely filthy. I feel this is unacceptable.

Both flights were delayed. I lost my connection on the way back. No voucher or anything was givenx I had business ticket and no support to make it on time. I got to the door running 5 min after they close. Food really bad. Breakfast in business was worst that I what I remember in economy. Even though I have accumulated many miles, I don’t think Inwill keep buying Iberia. I am a frequent business traveler.

The food is really eco only level. Breakfast was shameful. I am considering to stop flying with Iberia. Business prices are as expensive as other companies with much better service.

Why no entertainment? Also water should be free, it is basic human right.

Late boarding. Delayed departure leading to rushed connection at Madrid Barajas. Not necessarily Iberia's fault but delay loading cargo didn't help.

I can’t comment on food as it was necessary to buy it. No entertainment.

Took too long to tak off but besides that it was good

They made my flight a disaster they had me pay for bags that I already paid for through Iberia airlines and the hostesses were super mean and racist they just turned my vacation to a total nightmare and disappointment in fact they even had me rethink even no to go to morroco ever again even if my whole stay at the country was so nice and fun and perfect but anything at the airport and with the airline was a disaster do not recommend will never take a flight with them

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

The check at Accra was very bad . I had to be in the queue for solid two hours simple because your staff were pushing people and lifting the balustrade for them to jump the queue. This situation made us very made with your Accra check in crew. I have video of what I am putting across and I am happy I have the opportunity now.I can send the video to you if you are ready to punish those involved.

Connecting British Airways flight was 29 hours delayed so I never made it on this plane

No entertainment available on flight. Seating too cramped fir an average adult.

International flight from CCU to MIA . paid 1235 dollars at this low season. NO CHECK IN BAGGGAE ALLOWED ?????????????? NOT EVEN ONE?????????? Never ever I will even thing about buying tickets and flying with them again. Just A BIG NO

No food as per my diet restrictions even after advance request and delayed baggage without any notifications
