# How to find the tail number of a flight you flew

Ways to look up an aircraft registration (tail number) from a flight number, date and route, including flight-tracking history, and how to do it for hundreds of logbook entries at once.

You have a date, a flight number, and a city pair. You need the registration of the aircraft that actually operated that flight. Here is how that lookup works and where it breaks.

## One flight at a time

Flight-tracking sites keep a history of each flight number by day. Search the flight number, pick the date, and the aircraft registration is usually shown on the flight's page. The major flight-tracking sites offer this for recent history on their free tiers; older dates usually need a subscription.

This works fine for one flight. It does not work for a logbook: a five-year airline career is 1,500 to 2,500 legs.

## Many flights at once

Logbook Fix does the same lookup in bulk against a commercial flight-history database. You paste or upload your logbook, we match each leg by date, flight number and route, and return the tail number, aircraft type, ICAO codes and block times for every leg in one pass. Results are usually ready in a few minutes for a full career.

## Where lookups go wrong, and what to do

- **Two aircraft on one flight number.** Irregular operations sometimes put two airframes on the same number the same day. A good lookup shows both and lets you pick; if your logbook already had the tail, that settles it.
- **Returns to field and diversions.** Your logbook says BOS to BOS; the flight record says BOS to DEN, because that was the plan. Match on the departure airport and note what happened.
- **Late-night departures.** A 22:00 departure on the East Coast is the next day in UTC. Lookups that only use the calendar date miss these; use the departure airport's local date.
- **Ferry and repositioning flights.** Often filed under numbers public trackers never see. These stay as you logged them.
- **Bare flight numbers.** Exports that store "1171" instead of "NK1171" need the airline added once.

## Why it matters

Tail numbers are the one column in a logbook that an outsider can check against flight history. Interview panels, insurers and auditors use them to confirm that the flight happened, on the aircraft type you claim, on the day you claim. A logbook with tails is easier to trust than one without.
