It was meant specifically in respect to people taking the train to the airport, as that was suggested by a PP as a reason for moving the Mobile station.
You can't move something that doesn't exist at the moment.
The airport is doing the moving, from a truly terrible location not close to anything to right next to downtown. Setting up shop at the new airport sounds like a great plan. Will it work for everyone? Of course not. But it gives people options, and options are good.
