UA no longer have connections at LHR connections ex MAN!
If UA were pulling such volumes away from MAN they would address it since Red exited MAN-LHR
In the absence of Little Red, Star Alliance are happy to book connections to LHR with BA.
Not just United, many Air Canada fares via BA shuttle to LHR undercut their own Direct Rouge service, presumably to fill up all those 777 & 767s they operate from LHR.
The Manchester Rouge service to YYZ not only goes head to head with Air Transat but also their parent company via London. I just wished they (Rouge)had gone for Montreal from MAN where there is no direct service-unlike 40 years ago when BOAC provided a service.
I still hope the Rouge season this year is successful, but the handling needs to be substantially better than last year.
I'm connecting west Canada soon- all the Transat premium seats are sold out so, I am also being routed via BA to LHR to pick up AC from there.
