And another oversight in failing to acknowledge the glaring inadequacies of the LHR transfer experience.
It's completely rubbish. Just like T3 at MAN.
So having gotten that out of the way, might be worth addressing why
so many people keep doing it. That's your hard/soft product combo, T3 MAN on a 1988 build B763 fails on both counts. Nothing wrong with being a local supporter, it's not meant as a put down as many can debate well.
MAN is competing with LHR, so unless the product is half way decent, people can and do choose other options. Remember what a huge hit AA took when BMI came onto MAN-ORD?
