Question 1

How do airline alliances work and what do they get you?

Accepted Answer

An **alliance** is a partnership between airlines allowing them to cooperate on scheduling, ticketing and loyalty benefits without merging. The three global ones are **Star Alliance**, **Oneworld** and **SkyTeam**.

**Why they exist.** Regulation prevents airlines from simply merging across borders — most countries restrict foreign ownership of national carriers, and traffic rights are negotiated between governments. Alliances allow the commercial benefits of a global network without the ownership.

**What you actually get:**

**Through-ticketing across carriers.** The most consequential benefit. Booking a single itinerary on partner airlines means your bags are checked through, and — critically — if a delay causes you to miss a connection, the airlines are **obliged to rebook you**. This is exactly the protection absent when you book two separate tickets, and it is the main practical reason to book within one alliance.

**Earning and spending miles** across all members into one account.

**Status recognition.** Elite status with one member confers benefits across the alliance — lounge access, priority boarding, extra baggage, priority check-in.

**Coordinated schedules** at shared hubs.

**Round-the-world tickets**, which alliances price as single products.

**Where the benefits are weaker than assumed:**

**Codeshares are not alliances.** Two airlines can codeshare without being in the same alliance, and many valuable partnerships are bilateral. Conversely, alliance membership does not guarantee a partnership on every route.

**Benefits vary by tier and by operating carrier.** Lounge access rules differ, and the airline actually flying you sets the onboard experience regardless of who sold the ticket.

**Joint ventures are deeper than alliances.** On some transatlantic routes, airlines operate revenue-sharing joint ventures — effectively acting as one business on that route, with antitrust approval. This affects pricing more than alliance membership does.

**Low-cost carriers are largely outside** the system.

**Practical advice:** concentrate loyalty in one alliance if you fly regularly, and check that a connection is on a **single ticket** rather than merely on partner airlines.

Question 2

What happens if I miss my connecting flight?

Accepted Answer

It depends almost entirely on whether the connection was on a single ticket or two separate ones. This distinction matters more than any other in air travel and is worth understanding before you

Question 3

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 4

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 5

Why are some flights so much cheaper than others on the same route?

Accepted Answer

Because airline pricing is not a single price with variations — it is a system of fare buckets, restrictions and distribution channels designed to charge different passengers different amounts for

Question 6

What is a fifth freedom flight?

Accepted Answer

A flight operated by an airline between two foreign countries, as part of a route originating in its own — and the resulting services are frequently the most interesting ones in aviation, because

Question 7

What are air miles actually worth?

Accepted Answer

It depends entirely on how you redeem them, and the variation is enormous — the same points can be worth a fraction of a penny or several pence each. How to think about value. The useful measure is
