I think Sol is out at DFW, too. I looked at their Sept. pax figures and they carried 735 pax. That ain't cuttin it for any route, any size airline, plane, etc. Yet another foreign carrier to leave my DFW. I'd trade them for AF coming back, though. I'll see if I can make some phone calls.
Yes, Sol Air is gone from DFW. They only flew DFW-RTB once a week, so it is not a huge loss. Instead, they are now flying MIA-RTB non-stop instead of MIA-SAP-RTB. Overall, they have, however, done very well in the Miami-Honduras market, offering cheap fares in a high-fare market.
