We have been flying into and out of EIS frequently using FF tickets on United, American and Delta. We flew in two weeks ago on United. You need to call them; booking over the internet one-way from a foreign airport seems to be a problem. United seems to have better FF options for high level award program members.

United often connects to EIS using Cape Air. Other carriers use Seaborne more, but we’ve had good luck with both of them. All planes have been very full, and a lot of luggage has been getting left behind. At least four bags didn’t make it on our Cape Air flight.

The only major that has no connecting partner is Southwest. We play it safe by overnighting in San Juan if we use them.
