The "bailouts" were to make up for losses incurred when the government ordered all the airlines grounded following 9/11, as well as the cost of onerous security measures required upon restart.
There were no bailouts comparable to what happened with banks and car manufacturers. The Feds have been quite happy to let airlines go bankrupt and/or go out of business or get bought out and shrunk.
Except to the extent the government controls drilling, fracking, taxes and pipelines, they do not control fuel prices, either.
