Got this same "offer" via mail.
Phone # (855) 322-3037
Letter was brief, one paragraph informing of current eligibility to receive a flight benefit for two round trip airfares, and Included a"Boarding Pass Sample" at bottom of letter. This looked quite bogus, an obvious scam. I would very much like to know how they accessed MY name, etc.

Just received the same letter...though phone number is 1-855-538-5704.
Did not attempt to call...but clearly still in circulation.

Wow never spoke with someone more pissed off and rude when I tried to call and cancel my apt.  Clearly a scam I didn't catch on till I reserved a spot so when I called to cancel he went off and hung up on me.  I then called back to insure I was removed from their database and he said he was gonna file harassment on me for calling to much ha. I said ok I'll see u in court with my lawyer wow!
The number was 1 855 339 4244
Crazy stay away!!!!!

I received a letter today that I was eligible for 2 round trip airfares within the continental US.  I had to call and confirm by 9/24/13.   Number to call is 855-339-4236.   It looks like they change the number a lot.

I got the same letter from US Flight Reward. The phone number was  855-339-7863. Since they don't even know my first name I was highly suspicious. I'm over 65 and have gotten many similar letters recently. One even said I had won a French lottery but they needed me to come to France to p/u the money for a small fee. Can we say possible mail fraud>

Don't you just love the scammers! Unfortunately too many fall for it.

I got the letter with the phone number of 85-322-3040.

Thanks soooo much, I also received this letter, Called once all lines were busy, Please call back! I don't believe I will

Same info was received in a mailing except phone number is 855-322-3043

These idiots mailed their junk to a man dead four years hence.
Just another attempt to get you to join a travel club, waste over fifty dollars in non refundable deposits and attend a required 90 minute "travel" symposium.
STAY AWAY or just laugh at their stupidity.

This phone number was listed as the number to call to receive a "flight benefit of two round-trip airfares" from something called U.S.A. Flight Benefit Center. Googling this brought no results. The unsolicited letter I received also refers to the website www.americanbonuscenter.com, which consists of two pages and little information.

Clearly some sort of scam. Stay away!
