America West Airlines is offering a free BlackBerry 7100t to anyone who books a ticket on their Web site and activates service with T-Mobile until October 31.

“This is an ideal opportunity for the frequent flyer or anyone on the go — simply book a great fare at our easy-to-use Web site, activate a plan with T-Mobile, and receive a free BlackBerry 7100t,” said Travis Christ, vice president of marketing for America West. “Staying in touch while on the road makes our traveling lives easier, so we’re especially pleased to link booking with americawest.com with leading mobile-communication products and services.”

The BlackBerry 7100t, which retails for $399, includes phone, e-mail, Web browsing and instant messaging capabilities.

The promotion requires that you sign up for a T-Mobile service plan of at least $59.98 per month with a one year contract; however, you will receive a $100 mail-in rebate. It can be combined with other offers.
