Pennington, New Jersey -- Travelers' woes are rising along with gas prices this summer as United Airlines and US Airways join American Airlines in charging fliers $15 for a single checked bag. Travelers can fight back against airline baggage fees with five simple packing tips for people striving to pack efficiently and fly with only a carry-on.

1. Rethink the Wardrobe

Stick to wardrobe essentials. Choose clothes in neutral colors that can be mixed and matched, and pack a travel-size packet of laundry detergent to wash clothes while traveling. Bring no more than two pairs of shoes: one to be packed and one to be worn on the plane.

2. Simplify the Beauty Regimen

Don't lug an army of beauty products across the globe. Instead, use hotel toiletries or pack products with multiple uses, such as a moisturizer with SPF or a combination shampoo/conditioner. To meet security requirements, pack products in containers of three ounces or less in a quart-size, zip-top, clear plastic bag.

3. Pick One Favorite Guidebook

Don't weigh a suitcase down with books. Pack one comprehensive guidebook and use Internet cafes as necessary to look up additional information on the road.

4. Leave the Crown Jewels at Home

Leave all valuables at home. Fancy watches and jewelry are targets for thieves and can prevent travelers from fitting into the local culture.

5. Forget the Gizmos

Pack only indispensable electronic gadgets. Skip the toothbrush sanitizer, ocean sound machine and other extraneous items.
