Instead of the airport being hell bent on trying to get a route to India launched which is a very specific market and have been trying to do this for years, with the rumour almost cropping up on an annual basis.
What makes you think the airport is targeting an Indian route? It is only random rumours here that keeps the light burning.
El Al have stopped 787 into Luton because it cannot do the one way system, once the proposed new stands come online that might change
Don’t think EL AL have ever used the 787 into Luton, think your referring to the 777 but yes it’s prevented from passing the Easy hangar unless under tow.
I have never ever seen even their 737's use the bridge. All their aircraft use taxiway Delta to arrive and depart with a follow me vehicle leading the way. Remember there are the south stands available if needed for larger aircraft.
The airport has an issue in attracting any new airline to Luton as it seems focused on its existing carriers to provide growth.
