Orbitz
 

Never used Orbitz but an upcoming trip dictates I use them.

I bought a ticket from them under the impression I was flying US Airways (I'm a Dividend Miles with them and pay no baggage fees) to one city and then catching United to another.

The Orbitz email I got looks like I actually fly a codeshare flight on United on the first leg.

If in fact I'm flying United and not US, will they end up charging me for bags because its on a United plane?

Thanks
