Jayson, you're a fleet captain, and so was Pike.
Sure he's not an admiral or a commodore, but that rank denotes that Chris was in charge of a fleet, no matter how few ships it requires to make up a fleet, which would make Enterprise "a" flag ship since it carried a flag officer, for the brief amount of time between Pikes promotion, and Kirk assuming command.
By that reckoning, Admiral Kirk's presence should have made the Enterprise a flag ship, a ship carrying a high ranking officer, more so than the ship that assumes command of a fleet despite not having an admiral aboard.
