We looked at flights r/t from our local airport....and got the best rate through U.S Airways....but it still seemed a lot higher than normal....so, out of curiousity(and, even though no search engine showed any flights for..) I looked at United.com..since they fly in/out of our airport,but I figured they don't go to MoBay...what happened was AMAZING....they showed a r/t flights for the exact same days...for $800 cheaper than ALL the booking agents/sites....HOW CAN THIS BE?....turns out(after I booked us)...that the flights showed the EXACT same departure/arrival times as the U.S.Airways flights..even the same layover/connection in Charlotte....after printing out the reservation I noticed that, although the FLT#s were different...the fine print said "our partner airline, us. airways"...so we are gonna be flying on the originally quoted flights after all ...for $800 less!! I wonder why the industry works that way...it was just a fluke of luck for us...
