Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Klm start boarding while somw air issue in the plan

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.

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

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.

We were kicked off this flight by British Airways due to delays on our connecting flight also operated by British airways and were rebooked on a different carrier which delayed our arrival home by > 26 hours.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

I was put into business class. Wow! My flight attendant was great! The food amazing’

The gate at London Gatwick had confusing signs for the different zones and the staff seemed harried because people didn't know when it was their turn to come to the desk. Plus, with there were too many carry-on bag travelers, myself included. The charge scheme for checking bags is frustrating. If you travel light, you want the freedom to leave as soon as you deplane. When you are forced to gate-check your bag simply because the flight is fully booked, you lose whatever time you'd hoped to save because you're still stuck waiting for your bag to come off the conveyor belt.

Safe arrival. Improvement on Time efficiency Effective Communication will be great.

Not so good with their baggage handling as they damaged one of my check in luggage

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

All went well on the flight, not happy of course with having to pay for a seat and in hold luggage of £50
