                                          We had to deplane and take another plane and we arrived 2 hours after our planned arrival. Even so, the staff and the other travelers were very friendly and helpful.

                                          Jul 30, 2018

                                          We had reserved seats in the middle of the plane when we booked the flight. When we checked in, our seats were not assigned and had to wait until we got to the gate. We got there 3 hours prior to the flight and they gave us two seats in the last row next to 3 toilets. It was very unpleasant.
