United (an approved carrier) called me this morning to inform me that our flight (and son's flight which was booked through SATO) has been changed. It is not convenient, and adds a stop with a long layover. Lucky us. We want to change the flight, while remaining on the same flight as son if possible. Here is my question...what other airlines does CGA (SATO) use? Is it exclusively United? I don't want to make another reservation until we can get son's arrangements firmed up on Monday morning, but online I have found some good deals with Continental and Delta. Just wondering if there are other options out there. At any rate I can't really do much til Monday, but thought I'd see what you all think. Thanks!
