That's really worrying. I didn't believe earlier rumors that NOC were behind the current FR schedules. But either financial situation is poor enough to warrant limiting growth through awful schedules, or after a few good years NOC management are heading back to the bad old days.
I try to use NOC for all my travel, but for the last year I've had to use DUB more and more rather than lose 3 days downtime for a few hours business meeting due to in-frequency or late flight times. As I've said many times on this thread you can't even do a weekend trip to most of the current destinations and London ends up requiring a long weekend and back early on Sunday, the Monday morning offered some respite.
This is exactly the time NOC should be bending over backwards to facilitate a double daily or at least early morning schedule. GWYs well timed LTN services are gone, GWY/SXL/NOC PSO is gone, GWY airport may soon be gone, the opportunity is there to establish itself as viable option for anyone connecting or doing work in London.
