Cannot open certain routes S3B

now I cannot add flights to any competitive route. this is getting rough

Is the runway long enough for your aircraft you're trying to assign the route to? Are there any political restrictions? http://wiki.airline-...al_restrictions

If you could tell us the aircraft and the airports your are flying from and to, that would help us solve your problem much faster

I tried with everything from md-81, 737-3, 747-4d, and even q300, if a q300 cannot lan lax to sna something up, I found a work around after trying many things, if I only load a specific aircraft instead of all it seems to work, not sure what was causing it though.  Dfw-elp, was also having issues, along with about 30 other routes, it only seemed to happen on routes competitive with certain airlines some worked some did not.  Only suggestion I can give for finding the bug is maybe some sort of database issue with my 1k+ unassigned at the time.

You may be on to something here. Are you saying it works if you have a subset of aircraft shown when adding flights but not if you have 1000+ aircraft in the list at the time? And this only applies to certain routes but not others?
