On time, smooth flight, and crew attendants are very nice and helpful. Only draw back was the boarding process which I think was kind of awkward. My family seating was assigned on the same row, however my wife and daughter were boarded ahead of me as group 3 and I was boarded as group 5 (last). I thought it was an error by the airline at first, however, it happened again on the return flight but this time my daughter was boarded ahead of us when our seating was in the same row and next to each other. Other than that, every thing are good. Hope the airlines receives this feedback and make necessary changes.
