Question 1

Why is my flight operated by a different airline than the one I booked?

Accepted Answer

Because the airline that **sold** you the ticket and the airline that **flies** the aircraft are separate roles, and several distinct commercial arrangements separate them.

**The arrangements, which are genuinely different things:**

**Codeshare.** Your airline puts its own flight number on another carrier's scheduled flight. The operating airline's aircraft, crew and service; your airline's number and sale. This is the commonest case and is disclosed at booking as "operated by".

**Franchise.** A smaller carrier flies in the mainline airline's full livery and branding under licence. Passengers frequently never notice.

**Wet lease.** One airline leases another's **aircraft, crew, maintenance and insurance** together — the industry term is ACMI. The aircraft may be in the wrong livery entirely. Used to cover capacity gaps, seasonal peaks, delayed deliveries and groundings, and is the usual explanation when an unfamiliar airline's aircraft appears with no warning.

**Dry lease**, where only the aircraft is leased and your airline's own crew operate it — invisible to passengers.

**Subsidiary regional carriers**, which operate short-haul feeder routes under the parent's brand.

**Last-minute substitution** after a technical problem, where another operator's aircraft is chartered to rescue the flight.

**What actually changes for you:**

**The service and seating** are the operator's, which may be better or worse than what you expected.

**Baggage rules** frequently follow the operating carrier, and this catches people out.

**Seat selection and check-in** may have to be done through the operator, not the airline you booked with.

**Loyalty earning** depends on the marketing and operating carriers' arrangement, and can be zero on some fares.

**Lounge access** may not apply.

**What does not change:** your contract is with the airline that **sold** you the ticket, and that is who you claim from for delay, cancellation or baggage — a point worth remembering when the operator tells you to take it up elsewhere.

Question 2

What is a codeshare flight?

Accepted Answer

A codeshare is a flight sold by one airline but operated by another. You book with airline A, the ticket carries airline A's flight number, and the aircraft, crew and service belong to airline B.

Question 3

How does a flight number work?

Accepted Answer

It identifies a scheduled service, not an aircraft — the same number is used day after day for the same route and timing, while the actual aeroplane operating it changes constantly. The structure.

Question 4

What is a booking reference, and why does it matter which one you use?

Accepted Answer

It is the key to your reservation in an airline's system — six characters, letters and digits — and travellers get confused because a single trip can generate several different ones, only some of

Question 5

What is a fare class, and why can't I change my ticket?

Accepted Answer

Airlines sell many different fare classes within the same cabin, each with different rules — and the single letter in your booking determines what you may do far more than the price you paid

Question 6

What do budget airlines actually exclude compared with full-service carriers?

Accepted Answer

The headline fare buys a seat and very little else. The unbundling of everything previously included is the entire business model, not a series of petty charges. Typically excluded and charged for:

Question 7

What is an airline's conditions of carriage, and why should you read it?

Accepted Answer

The contract between you and the airline — setting out what each side is obliged to do, what happens when things go wrong, and the many things the airline is permitted to do that passengers assume it
