I thought about this earlier and thought I was going down the road of conspiracy theories, so I'm glad to see others thought this too haha. It makes some sense; people have a tendency to want to wait for the new thing, even if the new thing is just transportation from the airport. If they don't announce anything that's replacing ME most people will presumably assume there is nothing to replace it, and so there's no reason to postpone a trip. If anything it's reason to move it up. That might make people less interested in a 2022 trip, but that's not the year they care about right now.There could be numerous reasons why, but I think the most likely right now, is the concern that announcing a new service in 2022, may cause people to cancel/postpone trips in 2021. They desperately need people to visit NOW.
