I don't see the scramble on the 11:30.
You'll be in CA by 12:30
Assume an hour for customs give or take. That's 1:30.
15 minutes to the airport. 1:45....
Round all that up to a 2pm airport arrival and that still leaves you 3 hours to your flight.
Even adding another 30 minutes for delays, on a Wed I think 2.5 hours is feasible.
