I have my $100 Amex travel credit designated for Jetblue. I have 24 days to use this up. I have a flight in feb. which i would use this credit for baggage, but my wife had medallion status due to the status match. When we signed her up they said it expires 12/30/17 but I read from posts here saying they usually extend it the full year and should go through 12/30/18. What do you think I should, use the credit now and get baggage for that flight, or assume she will still be medallion status in Feb. and be eligible for free bags anyway, and use the credit for upgrading the seats?
