Don't forget the ‘3-1-1' rule. Contain liquids in 3.4 ounce bottles or smaller, fit them all into one quart-sized bag, each traveler is allowed one of these bags.
Valuables — cameras, jewelry, documents, medication — should be placed in carry-on luggage for safety.
Label suitcases on the interior and exterior with a name and cellphone number.
Have destination's address easily accessible in case luggage is delayed.
Flying early or late in the summer travel season makes finding cheaper fairs easier.
Flying on less popular days — like Wednesday or Saturday — can also be less expensive, or during less popular times like midmorning, lunchtime or dinner time.
Flying connecting routes can also reap big savings.
Airlines no longer accept cash, so don't forget a credit card for purchasing other food items on board.
If traveling with kids, bring plenty of diversions for them — like games or snacks — in case of a long layover.
Wear comfortable clothing and shoes. Planes can also be cold, so it's wise to dress in layers.
