I like the crews’ services, especially for sr citizens who were on wheelchairs, the efficient pilots with their smooth landing of the plane back and forth, cleanliness of the restrooms and other amenities provided to the passengers! Flights were on time it’s fine with a little bit delay but we arrived on time!
