Local news did a story/ad on this service yesterday. It was the first I have seen of the actual buses - they are AA-branded, look nice, and have 2x1 seating so presumably they are pretty roomy. Still can't see myself using it, but it does seem like they are trying to make it an upscale experience (or at least more upscale than American Eagle). As TPG reported, they also noted airside connections won't be available "for the first few weeks".
