Similar type situation I'm looking at. JFK-DCA on American is absurdly high $249 one way. JetBlue is available for $70.
Arrival on Iberia at T8 at 6:50 pm. No GlobalEntry but have MPC. No checked baggage. WIll be in Business so I will be off early. JetBlue connection out of T5 at 9:30 pm. I do have Precheck.
I assume that 2:40 is sufficient on this one?
