I just saw on the local news (WORA-TV/Univisión) that American Eagle is planning to end service to Mayagüez, Puerto Rico's Eugenio María de Hostos Airport just after the new year. Without American Eagle, the airport will have no airline service whatsoever. The reporter interviewed some people in line for check-in and none were happy to hear that the San Juan-Mayagüez route might end. The reporter went on to say that the Ports Authority will try to keep AE in Mayagüez, but is allegedly trying to get another airline to fill the void.
I also found the possible end of Mayagüez's service mentioned in this Caribbean Business article: http://www.puertoricowow.com/html/cbarchivesdetail.asp?id=14355&highlight=
I'm glad I had a chance to fly this route before it's ended. It's sad, though, that Mayagüez will lose the only service it's had for years. It's a nice, tiny airport, and even though I got delayed four hours, I would've gladly flown American Eagle from there again. But I guess with BQN in Aguadilla starting to grow as it is, it was just a matter of time before Mayagüez suffered.
