Well maybe - sort of?
T-Mobile is offering a free airline ticket to customers that sign up for new service or re-up their contract for another 2 years. To make things difficult T-Mobile decided to offer the deal on the three busiest shopping days of the year, November 23rd, 24th, and 25th. Of course with any offer of this kind there will always be certain restrictions and guidelines to follow in order to take advantage of the deal, so make sure you read through the Terms and Conditions carefully.
Don't expect to be handed a voucher for a ticket the same day you sign up. There is a three month waiting period in which your account must remain in good standing and have met all of the qualification requirements in order for you to receive your ?Free Flight Booking Request? form.
