For travelers, the most obvious effect of airline alliances is codesharing whereby one airline will sell a seat on a flight with its own flight number, but the flight is performed by a different airline. (Note that not all airlines are part of an airline alliance, and not even all airlines within the same alliance do codeshares with each other.)

Although many airlines in an alliance have subsidiaries, the subsidiaries are often not members of the alliance which the parents are part of.

How does this apply to me? edit

• Airline alliances tend to coordinate their flights to ease connections, flying intercontinental flights to each other's hubs, adjusting schedules and grouping one alliance's flights at a single terminal at large airports. They code-share and interline (transfer bags) with each other, so that you can travel to many more destinations on a single ticket sold by your local airline.

• You can collect frequent flyer miles when flying on an alliance partner airline. This means for example that a passenger with Qantas can claim mileage when flying with another OneWorld airline such as British Airways.

• Additionally, status levels that you have on one airline are generally recognized by other airlines in the same alliance. For example, a 'Morning Calm' status with Korean Air will automatically give you 'Elite' status when flying with another airline in the SkyTeam alliance. Thus, you can check in at the Business Class counter, get priority luggage tags, getting emergency exit row seats assigned to you and priority boarding of the aircraft.

• Travelers can take advantage of a round-the-world ticket, a ticket with the ability to stop at a few countries around the world for a relatively lower price.
• If your trip is interrupted by a flight delay or cancellation and has a connecting flight that you will now miss due to the interruption, airline staff may rebook you on another airline's flight from the same alliance to minimize the delay in reaching your final destination.

Oneworld is the smallest alliance counting by the number of airlines. The member airlines are spread evenly around the world, so it is a workable option when planning a long multi-point trip such as for a round the world flight. It was the first alliance to introduce interlining e-tickets.

Star Alliance is the world's largest airline alliance.

Cooperation includes seamless code share flights and baggage interlining and, as a new trend, an increased degree of co-location in airport terminals.

Members of any Star Alliance frequent traveler program (FT) can credit miles or points flown in many booking classes on any Star Alliance operated aircraft.

"Gold" Star Alliance FT members get an extra 20 kg or "piece" of baggage; reciprocal access to most Star Alliance members' lounges; priority boarding and priority wait listing.

Main article: Frequent flyer programmes

You should choose your Frequent Flyer airline in an alliance carefully. Although you may think it is intuitive to join the airline you fly most, you should be aware that privileges offered are often different and frequent flyer points may be more generous under a different airline in the same alliance.

By way of example, to reach Star Alliance Gold status (affording you priority wait listing and boarding, extra checked baggage allowance and use of lounges even when flying on any Star Alliance economy flight) requires only 20,000 miles in one year with Aegean Airlines' Miles&Bonus program, but some other member programs require 50,000 or even 100,000 miles in a year to be flown before awarding Gold status.
