Illegal? no such laws....

tacky? I don't see it that way, YMMV.

if somebody paid $10K for the same flight that you paid $500, I think they deserve little more consideration, as in getting to passport control first, having their luggage first and getting out of the airport ASAP so they could make some more $ to pay for another F ticket.....it's just business......

You do realize that airlines also provide "Special Services" to the big spenders. That usually includes an escort services through security, a baggage valet, a personal valet upon arrival, a cart ride to the connecting gates, etc.... I just thought you should know.....
