Thanks!

Jetblue does NOT interline.... therefore only went into lounge for literaly 90 seconds, when the flight was called.... I actually almost missed the cut of for check-in, but made it and also got op-up to F (on a WT+-CW MFU), they also up'd Miss yyzlhr to F - who was on points (CW), at the desk, when they told me I was op-up'd.

Very nice staff at IAD!!
