How to Avoid Paying Airline Baggage Fees

As a result of skyrocketing fuel prices, United Airlines (UAUA) and US Airways (LCC) both plan to follow American Airlines' (AMR) lead and charge passengers $15 just to check one bag. (These moves come just months after six of the major airlines started charging $25 for a second checked bag).

"Most of the remaining airlines are probably going to jump on the bandwagon," says Ed Perkins, contributing editor for SmarterTravel.com, a travel advice site. Continental Airlines (CAL), Delta Air (DAL) and Northwest Airlines (NWA) have yet to rule out adding similar first-bag fees. The rare exception to the carriers' fee-centric mentality: Southwest Airlines (LUV). In what now seems to be a very prudent move, the airline locked in gas prices eight years ago, affording it the ability to be the only major airline that does not charge for either of the first two checked bags.

"[Air travel is] truly becoming an a la carte business right now," says airline expert Terry Trippler, owner of booking site TripplerTravel.com. "You're paying for the flight, and everything else is extra." (If the thought of paying to check a bag makes you reach for a stiff drink, bear in mind that US Airways will also begin charging $2 for once-free on-board beverages like sodas, water and coffee. Alcoholic beverages, previously $5, will be $7 after the new policy takes effect Aug. 1.)

With a little strategic packing and forethought, savvy travelers can send their bags packing without paying too hefty a price. Here's how:

Embrace the middle seat
It usually has the most under-seat space, ideal for a squishable duffel, backpack or small rolling briefcase, says Susan Foster, author of "Smart Packing for Today's Traveler." (The plane's curvature reduces space under window seats, while aisle seats have condensed space to allow for wider aisles.) The catch: Some airlines store electronics or other equipment under the seat, so check with your airline first about maximum dimensions. Many offer this information outright in carry-on bag restrictions, but you can also find it in the airline's policy section on traveling with pets — on-board carriers must fit below the seat.

Board early
If you're worried about getting that space in the overhead bin, know your airline's boarding routine — and make sure you're among the first in line for your section. Most carriers allow passengers with disabilities and elite frequent fliers to board first. Northwest offers open boarding in no particular order, while Delta often starts with the window seats in the back.

Be aware of carry-on limits
Airlines are cracking down when it comes to carry-ons. American, for example, limits bags to 45 linear inches (length plus width plus height) and 40 pounds. It also permits one small personal item, such as a purse or briefcase. (Child safety seats, strollers, diaper bags, small bags of food, wheelchairs and walkers are exempt and may be brought on additionally.)

Check airline exemptions
American and United waive first-bag fees for first- or business-class passengers and elite frequent fliers. All major carriers still allow two checked bags for flights with an international leg. You might also be exempt if you bought your ticket before the new fee goes into effect. US Airways won't charge those who purchased tickets before July 9. Consider planning future trips on an airline that hasn't yet announced a first-bag fee.
