Klm start boarding while somw air issue in the plan

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful
