Every ship in the fleets below, counted from its first passenger voyage to today, or to its last day in service. The figure keeps climbing while the sailing fleet is at sea.

Cruise lines do not publish a lifetime distance for each ship, so no source lists the true number. Each total here is calculated from the ship's in-service dates and the kind of trips it usually sails.
Miles = days in service × share of days under way × nautical miles per day. A ship is counted as under way 92% of days, which leaves room for dry docks and port repairs. The daily pace depends on where the ship sails, using typical one-week itineraries for each region. A ship that splits its year, such as Alaska in summer and the Caribbean in winter, gets a blend of both, plus an allowance for the long positioning voyages between seasons:
Fleet-wide shutdowns are included: almost no sailing from mid-March 2020 to the end of June 2021, then a partial restart through the end of 2021.
Real voyages wander. Ships divert around storms, turn back for a medical emergency or a person overboard, join a search or rescue, or loop to arrive on time. None of those extra miles are recorded anywhere public, so they are not in the totals. A ship's true distance is likely a little higher than its estimate.
Treat each total as accurate to within roughly a quarter, higher or lower. Ships that spent years on short Bahamas runs sail fewer miles per day than ships on long Alaska or transatlantic routes, and the pace figure averages that out. When a year is the only date we have, we assume mid-year.
Each ship's page shows where it typically sails. For ships marked "2026 schedule confirmed", we checked that region against published 2026 and 2027 cruise schedules. For the rest the routes are estimated from the line's usual pattern. Ships change regions over the years, and we apply today's routes to the whole career, so older totals are the least certain.
Fleet lists, entry years and tonnage come from public fleet records and may differ by a year from a line's own history. Ships that moved to another line are counted once, from their first day in service, and the note on their page says so.
