JetBlue TrueBlue - Do I get double TrueBlue points if I don't provide my TrueBlue # at time of booking?

I booked a ticket online recently and didn't have my Trueblue number on me at the time. I called Jetblue a few hours later to add it to my PNR. Will I still get double points for an on-line booking?

I'm not sure, but on your itinerary, it says that you booked it online, rather than at an airport or over the phone. So I'd assume they would use that info to decide if you get double points, but I'm not really sure.

I traveled last weekend, and did not provide my TrueBlue number until at the gate. I got double points.

Which means, of course, double the fun watching them expire. :)
