Inconsequentially priced food. Bought a bottle of water for at least 3 at Starbucks , nearby vending machine sells same size bottle for about 1,50. Doesn't make sense, pricing should be the same within airport. Also we came from Havana where we already went through security, transferring to flight to London we had to go to security again, we didn't leave the airport, so I don't see the logic of this. Check-in procedure was super unorganized on in and outbound flights. i am not sure if this falls under the responsibility of the airline or airport. There were 3 or 4 queues cordoned but no signs saying which boarding group should be in which queue. This resulted in chaos when boarding started. Logically Boarding Group 1 was asked to board first, however all were dispersed at the gate. This could have been prevented easily by putting up signs at the gate, Boarding Group 1, queue 1 etc. etc. Our return flight was delayed by 3 hours, due to air traffic control in France, fair enough but no announcements were made and the flight get on getting postponed. This baffled me, why leave people in mystery. The screens mentioned the delays but that's not enough for a delay this long. Would have given one star, but one extra because of nice layout of airport, very unclear which gate is where though.
