We've got a great deal on Norwegian flights from LGW to SJU, too good to resist so we're heading back in March. Has anybody got any experience yet with Norwegian? Flight arrives at 18.30 into SJU and the last Cape Air flight is 8pm. I'm wondering if 90 minutes is going to give us enough time to clear immigration and then make that 8pm flight, or do we just relax at the airport hotel and get a morning flight.
