Honestly, Chekov never knows what to call people on his own ship. They've been together long enough that the command crew should, in theory, be on a first-name basis, but Sulu--and, in the City, Uhura--are the only people Chekov is comfortable calling by their given names. Everyone else, with the exception of Scotty who will happily correct anyone who neglects to call him Scotty, is addressed by rank, surname, or both.

No one calls him Pavel at home.
