(I include SEN because Aer Arann has plenty of PSO experience and might fancy
being indirectly subsidised to fly a couple of daytime routes out of
SEN.)
Cyrano; I think you could be onto something here, and given that RE did attempt to launch Luton Newquay before this may have merit. Without a competing service and a PSO they could find it tempting. Moreover, a possibility to work the flights in with a DUB or ORK connection on some days, as these routes have operated in the past with some success.... albeit seasonally.
