Today i received my second letter telling me my FC number and that ill receive my new "snazzy" card after my first flight. Is there any reason i have had 2 of the same letters with the only differnce being the letter head has changed to the new card style[?] and how long will it be till i get my card i few to lax a month ago i was hoping i would have my card by now!
Thanks,
Chris
