Flight Itineraries
What a flight itinerary is and how to read one
A flight itinerary is the plan of your journey: which flights, on which dates, between which airports. It can describe a trip you’re still planning or one that’s booked. Reading it carefully is the cheapest way to avoid a missed flight.
A flight itinerary is a list of the flights that make up a journey: for each one, the airline and flight number, the departure and arrival airports, and the dates and local times. Put simply, it’s the plan of your trip by air.
The word covers two situations. Before you book, an itinerary is a proposal: the flights you intend to take. After you book, the airline or agent sends you an itinerary that describes a booking, with a booking reference and, once paid, a ticket number. Same layout, very different status.
Itinerary, ticket and boarding pass
| Document | What it is | When you get it | Can you fly with it? |
|---|---|---|---|
| Itinerary | The plan or record of your flights | When planning, or as a booking confirmation | No |
| E-ticket | The airline’s record that you’ve paid, with a 13-digit ticket number | After payment and ticketing | Not on its own: you still need to check in |
| Boarding pass | Permission to board one specific flight | At check-in | Yes, with your passport or ID |
Many airlines combine the itinerary and e-ticket receipt into one email, which is why people use the terms loosely. The difference between reserving and ticketing is covered in reservation vs ticket.
How to read an itinerary, step by step
Take any itinerary, planned or booked, and go through it in this order. Our annotated sample itinerary shows each of these fields in place.
1. Check the names and the status
On a booking, the passenger names should match passports exactly. The status tells you whether seats are held, confirmed or ticketed. No ticket number usually means no ticket yet.
2. Read each flight as one line
Every flight, or “segment”, has an airline code and number, an origin and destination airport, and a departure and arrival time. A journey from Karachi to Toronto via Doha is two segments, even if you bought it as one trip.
3. Decode the airport codes
Three-letter codes are compact but easy to misread. LHE is Lahore, LHR is London Heathrow. Cities with several airports can catch you out: London alone has five or more with scheduled flights. If a code is unfamiliar, look it up in the airport code finder.
4. Treat every time as local
Departure times are local to the departure airport and arrival times are local to the arrival airport. A flight from Dubai at 09:30 that lands in London at 13:15 hasn’t taken under four hours; Dubai is three or four hours ahead of London, depending on the time of year. The time zone planner does this arithmetic for you.
5. Look for “+1” and overnight flights
A “+1” (or “+2”) after an arrival time means it lands that many days later, local time. Check that hotels, transfers and onward flights use the arrival date, not the departure date.
6. Check every connection
Work out the time between landing and your next departure at the same airport. Watch for:
- terminal or airport changes, which need more time;
- separate bookings, where a delay on the first flight isn’t the second airline’s problem;
- overnight connections, which may need a hotel or a transit visa.
7. Note who operates each flight
If a segment says “operated by” another airline, that’s the airline you check in with and whose baggage rules may apply.
Planning an itinerary before you book
Laying out an itinerary before paying for anything lets you test the plan: are the connections realistic, do the arrival days work, does the trip fit your leave? The flight itinerary builder does this for one-way and return trips, and prints a sample marked SAMPLE · NOT VALID FOR TRAVEL so it can never be mistaken for a booking.
Questions people ask
Is a flight itinerary the same as a ticket?
No. An itinerary lists flights; a ticket proves they’ve been paid for and issued. A booked itinerary may include the ticket number, but the itinerary itself isn’t the ticket.
Can I check in with just my itinerary?
You check in with your booking reference or ticket number and your passport. The itinerary is where you’ll usually find those codes.
Why does my itinerary show a different flight number from the airline I’m flying?
It’s probably a codeshare: one airline sells a seat on a flight operated by another. The “operated by” line tells you who’s actually flying.
