I though of this from the post about the problems with us airways. I was wondering if they do go out of business the US could use the airline as a chip to gain openskys between the UK and US. They could agree to letting BA buy US airways in exchange for BA giving up LHR slots and also letting the other major airlines in the USA who want to fly LHR do so. This would also let bmi to fly UK-US flights from LHR and also let VS set up there American low-fares airline Virgin Red and everyone wins and gets what they want.
Would this work?
