BCN-AMS return on A320. Overall happy with experience although as others have noted this is a low-cost carrier so expectations should be kept low as per inflight service. Checked in online no problems. Purchased extra-legroom seats they were honoured and had loads of space although it should be noted that these seats do not recline so you are also losing some comfort. The return flight was not full and some passengers moved to these seats for free but then again its only 12 euros extra. Flight attendants were young friendly and professional. Flight to Amsterdam left the gate more or less on time but spent 20 minutes taxing to the runway. Flight back left nearly an hour late due to incoming flight arriving late in fairness they did an incredibly fast turnaround and they apologized for the inconvenience. Would not want to use them to connect to an intercontinental flight but for leisure travel will use again.
