A codeshare agreement means that cooperating airlines are able to sell seats on each other’s flights. This means that you are able to travel to more destinations than your airline of choice normally offers. Codeshare flights are also beneficial because of the seamless transits you can get with connecting flights from the same airline. The downside of choosing a codeshare flight can be that you in some cases can’t upgrade codeshare flights or use elite benefits.

A connecting or transit flight means that you reach your final destination through two or more flights – in other words a non-direct flight. You will change to a new aircraft after your first flight, this may include moving to another terminal at the airport aswell. The time required to transfer passengers and luggage between flights is called Minimum Connecting Time (MCT) and are always taken into account here on Flightroutes.com.

If you bought your whole flight on a single ticket, the airline will book you on the next available connecting flight.

With connecting flights, checked in luggage is most commonly forwarded to your final destination when buying a single ticket for both flights.

If you miss your connecting flight due to circumstances outside your control such as your first flight being delayed, you should turn to your airline who will provide you with a seat on the next available flight. This is usually done free of charge, and only applies if you purchased your trip as one ticket. If the next connecting flight is the following day, the airline usually provides accommodation and meals.
