A hard truth: you are not in an alliance because your airline is neither large nor healthy enough for anyone to want you right now. Moreover, getting into an alliance will not help your cash flow at all, and indeed, what little LF boost you get will likely be offset by the alliance fee. If you want to get out of the red, I would suggest not flying to heavily competed routes like Atlanta, and with your ATRs, double up your flights on uncompeted routes, and drop those that are competed and fly to Buffalo, Norfolk, Louisville etc. -- slightly smaller airports within c.500 miles with 50-60 pax demand and no competition. Use your MD80 for longer routes, but again, not Atlanta or other heavlly competed routes because you are getting killed there because you don't have the frequency of your competitors. Once you have secured decent RI on uncompeted routes, your cash flow will get out of the red and you can expand again, but I wouldn't expect alliances to be very interested in you until you have a fleet of at least 25 aircraft.
