Your post is way off. I didn’t quote the rest because I didn’t want anyone reading it again.

United only flies from MCO to its hubs. It’s no different than any other outstation. It became a single fleet pilot base because it has a lot of flights (and will increase once TPA is added to the base), so it made a lot of sense to add it as a pilot base.

United has no plans to add any non-hub flights to Orlando. They tried this during COVID and have since removed them. Even if they did add some flights, it would only be a handful of high traffic point to point legs. United is not planning to route connecting traffic through MCO.

United already moved some of the connecting traffic from EWR to IAD a few years ago to reduce the strain on O&D traffic at EWR.

United would grow EWR if they had the capacity. Unfortunately this time it wasn’t lack of capacity or gates that caused the meltdown, but a lack of ATC staffing, which is planned to be fixed by next summer. I bet this past week doesn’t change United’s plan at EWR at all.
