I don't think thats even possible anymore. I do think that when you purchase a ticket you should be given the aircraft name instead of a strange code like 73G or CR9. A little truth in advertising.. Its should simply say "Delta Airlines Boeing 737-700" or "operated by Mesa Airlines Canadair 900". The affiliate airline should have a hyperlink to the corporate website.

I used Delta as an example...I don't mean anything by it.
