Dear US Airways,
I'm at the airport two hours early as prescribed by current advice. Nobody is at your checking desk so I can check my bag. I would say this was strange, but oddly enough I don't expect better from you.
Your pissed customer who will make it a part of his profile to never fly you again.
edit PS if the recommendation is to arrive 2 hours early, then you should schedule your workers shifts to start 2.25 hours before the first flight.
