The lack of leg room for a 6 foot person makes for an extremely uncomfortable flight over the pond. Short little puddle jumper from Paris to London and back no big deal, but nine hours in a tiny and unbelievably hard seat makes me not want to do that ever again. This is my third trip to Normandy. FYI.

The lack of leg room for a 6 foot person makes for an extremely uncomfortable flight over the pond. Short little puddle jumper from Paris to London and back no big deal, but nine hours in a tiny and unbelievably hard seat makes me not want to do that ever again. This is my third trip to Normandy. FYI.

It was fine, seats were entirely too small. I’m not a huge man, and my hips barely fit in the seat.

In London, everyone was very helpful to make sure all passengers find the next aircraft, as everybody missed their connection due to the late departure in Miami. My mom‘s airplane left two hours after her arrival to London however, for my nephew they only had room on the next flight seven hours later. In the last minute they contacted him and was able to put him on the same flight as my mom./ which we were very thankful for Therefore, all his luggage was on the other aircraft and have not reached Budapest yet.

Quick boarding process, slight delays on the tarmac prior to takeoff and a late arrival due to an emergency on the landing runway. Not the fault of the airline at all! Cabin crew was very friendly and the Captain kept the passengers well informed about what was going on

Seats did not recline. That is none of the seats on the plane are designed to recline. If you want food you need to purchase it. We flew round trip Warsaw to London- both flights were late.

The port to insert the headphones was loose and had to hold it the entire time

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

During breakfast the fligh attendants missed one side of the plane for tea/coffee. I was on the other side and received tea. Unfortunately my husband and friends did not.

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Better and more attentive crew and more food options. Leg space is very tight.
