Given how well Luton is doing without a rail link to the station and pre-expansion just imagine how well it can do with a rail link and once expansion happens.
For me, the improvements to the airports infrastructure would be incomplete without the rail link. It improves the customer experience significantly and creates an even stronger case for airlines to come to the airport.
They'd be foolish not to seize the opportunity of pushing through with the rail link this time. Thankfully, it seems as though the major parties involved are committed to making it happen at last.
