No your screwed. And rightfully so. 
Errm lets see.... without checking, I seem to recall that Avalon airport has less than 500,000 pax. There are people around on these forums who suggest not basing at an airport which has under 10 million pax.
I think you should just cut your losses and shut the base.
Wow, I don't know how tense things get now with multiworlds (remember, I just came back to playing), but I based all the time out of airports with less than 10 mil, and I found it very easy to be profitable (My frist base is just under 200K), though you will get a very small profit if you fly to towns the same size as your's. Really, when you get pax numbers lower than 150K in each airport, then that is when you should avoid basing there. When you get in the airports that typically are above 10 mil pax, things are known to get insanly tense rather quickly I have heard. I think the best range for an who is not all too well experianced with the game or want to avoid the tense situations in the world's LHRs and CDGs is between 180K to 8 million.
As suggested, just ditch the base, as it's far below what would make a reasonable profit (reasonable profit meaning to give you a positive amount in the Fiance for the end of the month, rather than a positive amount in the "Create route" screen.)
