I think it has something to do with applying for the card when you are booking a ticket. If you start to book a ticket, before you click the button to submit, there will almost always be a credit card offer. If you sign up for those, I believe you get an instant number. When I had my mom sign up that way a couple years ago, she got an instant number we used for the purchase. I was looking just the other day at one of those offers and I remember reading something about being able to use a portion of the credit immediately.
