Skyauction airline?
 

I am looking at buying this business class ticket at skyauction.com

Of course they tell you it is a "major U.S. airline" but not more specific. It does say, however, that it allows stops up to 3 days in either New York (Newark) and Houston. So, I am guessing these two cities are the hub for this mystery airline,

Can anyone tell me which airline uses these two hubs? And how is this airline's business class service?

I'd guess Continental.

that would be my guess too, since Continental uses Houston as their hub.

Can anyone tell me how is Continental's business class service?

Many threads answering that question over there.
