I had to get htis one out, quick! It says the tickets do not expire, however, I think the deadline to complete the questionnaire, does. So, 2 free airline tickets!
For whomever checks into this... Please share with us if there is a catch, how it works, how difficult it is...And, are there restrictions? I can not personally endorse because I won't be taking a trip anytime soon. My husband broke his leg recently at work, so he is non ambulatory!
