Swiss International announced an improbably codeshare arrangement with US Airways. Swiss will put its code on the US Airways flight from Philadelphia to Zurich and US Airways will place its code on a group of continuing flights from Zurich.
I have flown in coach and business class on both airlines. Swiss passengers are going to be disappointed and US Airways passengers will think they have died and gone to heaven.
Unfortunately, the longest leg in these codeshares is between Philadelphia and Zurich. US Airways will have to upgrade its coach and business class service to match the Swiss customers expectations.
