I think that people who said that TWA is doomed have not seen the load factor for the last 3 or 4 months (80% in july and august) and that result is coupled with 10% more ASM.

What TWA cannot do is compete on high concurrence and low yielding route that are not O&D St-Louis (Karabu). When you have someone that make NYC-Florida for $79 and you factor the discount of Karabu ticket...
Probably TWA got no more than 50 bucks for that ticket They are redeploying their fleet where there are more money to be made (don't forget that the ASM year over year is up 10% so they fly more than in 1999) and the number of pax emplaned for the last 3 months is up by about 5%.

If they can get past Karabu (october 2003) they will do it.
