Dress comfortably - you will be on the plane for several hours. Don't forget to pack a sweater as the AC is usually on high!
You might want to make a trip playlist, bring some books or magazines, and always remember to be respectful of other passengers and crew.
Remember that delays and changes are common when travelling, so it's best to roll with the punches! Try to make the best of your travel time and remember that you are only hours away from the #tripofalifetime!
