United was offering this option as I used miles from EIS to ORD in June and November. Suddenly they had stopped offering award travel to the island. STT is an option but adds 3 hours to my travel time. United goes non stop SJU to ORD and gets me home at about 6:30 at night vs AA out of STT that tops in MIA and hits ORD @ 9:45.
For me American in via STT and out on United from EIS works best.
Thanks for the IC option, I forgot about them.
Can anyone give any reasons why not to book a smaller carrier to SJU direct that fly another major airline home? I usually have just booked both flights under one carrier. Not sure if there are any risks not doing it that way.
