I received the same postcard with Southwest Celebration on the cover and a photo of an airliner. Only two round trip airfares are offered, but to anywhere in the continental United States. I think I'll pass. Thanks for your post.

Not a phone call, but a postcard.  "Congratulations XXXX. We have selected you to receive four (4) round trip, coach class airline tickets to over 30 of the most popular destinations.  To verify your eligibility, simply call 1-570-299-2190 or 1-844-248-0001 weekdays 11:00 AM to 8:00PM.  Mention promote code XXXX.  Call within 48 hours and also received a 3 day 2 night stay for up to four(4) at the most popular destinations."

No company name other than a header "AMERICA's VACATION CELEBRATION".

Fine print says hidden against a dark background says "Offer is limited, may be withdrawn at any time without notice, and restrictions & qualifications must be met to receive your gifts [Note: above language does not say the tickets are gifts, does it? Do they maybe give you a $5 token instead?]  Call for complete details. Attendance at a timeshare presentation is required to receive offer.  This advertisement is being used for the purposes of soliciting sales of timeshare interests.  Complete offering terms are in an offering plan available from the sponsor"
