I was under the impression that AZ had already sold their LHR slots and the airline was still using them under a lease agreement, but I think any possible move will be to LGW now slots have become available due to the collapse of Monarch.
As to slots, are the former Monarch slots owned as everyone seems to state especially at LGW, is there any monetary value to these slots or are they just put back into the pool and redistributed to other airlines?
