Let someone else book your domestic air plane travel ticket

If you're willing to pay a few extra fees, you can let a travel agent handle the entire headache for you and book your domestic travel air fares. Once you've found a great agent that works well for you, don't let him go.

I recommend: You may be entitled to a travel agent's services and not even know it. If you're a member of a service organization like AAA, they offer travel agency assistance as a membership perk. Willett Travel offers a specialty in corporate travel.

Book a domestic airfare ticket when it suits you

If you want complete control over your own travel reservations, consider using aggregate travel sites that let you select your ideal itinerary, then find an airline that fits it.

I recommend: Aggregate internet travel websites like Mobissimo and CheapOair let you search for flights according to factors like flight times, schedule, seating class and number of stopovers. They often offer opportunities to purchase package deals on hotel and car reservations. Mobissimo also lets you see and select low fares that other clients have recently found.

Get your domestic air plane travel information directly from the source

Sometimes purchasing directly from the vendor--in this case airlines--gives benefits in terms of convenience or even cost. Consider joining a membership program or frequent flier program, and using the miles or rewards you accumulate for personal or business travel.

I recommend: Delta and American Airlines both offer reservations, flight planning and frequent flier services through their websites. If you're having trouble booking the flights directly, you can also call the reservation desk for assistance during business hours.
