We transited SJU yesterday.
Silver Air (JetBlue codeshare) EIS-SJU 3:10pm
left on time.
plane (Saab turbofan) must have been built in the 1970s
no air conditioning.
ugh.

they forced our "plane check" carryon to the baggage carousel in SJU, for customs inspection.

My entire family has global entry -- it took longer to use global entry kiosk vs. just going to an immigration officer.
BUT -- it was almost instant. Gave passport and GE printout to officer, "do you have any produce?" Off we went...

WHERE IS THE bag drop to send transiting checked bags to final destination?
No longer.

SO we had to lug our stuff to the main terminal -- and JetBlue is in TermA. More lugging.
Then a short line at FDA, then to Jet Blue.

We had PLENTY of time.
Left Nanny Cay 12:30pm, arrived EIS 1pm, checked in by 1:10pm, lunch pre-security.
At gate by 2:30pm
Boarding at 2:55pm

You can be 100% certain they will not leave without you -- the plane that you fly out on comes directly from SJU. The crew remains on board. They turn this plane around in 10 mins.
