The only way US Airways or United obtains revenue in the code share is when a passenger travels on their airline.
If US Airways and America West merge and code share first, if US Airways reservation agents book a flight on Untied and the passenger could have flown on US Airways-America West to their final destination, then US Airways would give the revenue away to United.
Expect the merger to be announced very soon and a holding company to be created. The holding company will be controlled by third party investor(s) and any revenue obtained by US Airways – America West would become the Holding Company’s revenue.
Once the code sharing and merger are complete, US Airways -America West Holding company agents for the combined business enterprise must book flights on the combined business entity first, and then Untied, if both companies serve a common destination, so the US Airways – America West holding company obtains the revenue.
