No, they are just historical routes, and will be cancelled in due course, this summer the schedule was there as normal and cancelled prior to commencement, initially prior to each month starting, and then the whole of the summer schedule was cancelled. LHR has just ramped up to 5 a week, from the previous 5 per day, and going daily from July. Plus almost all at MAN were made redundant!
I could be wrong, and I do hope so, but don't see it happening this year. You can't even get in HKG unless you have residency, and have to currently isolate for 21 days! Plus it's a red route so only essential travel from/to the UK. You may see a few student flts, that's about it at the moment. Sad times indeed.
