Book Connecting Flights with Different Airlines

Planning a trip that requires more than one flight? Sometimes, the best route to your destination may involve flying with two or more different airlines.

At ThaiFlightCenter, we help travellers search for connecting flight options across multiple airlines, giving you more flexibility when a single airline does not operate the entire journey.

Whether you're travelling within Thailand, around Southeast Asia or connecting to an international destination, combining flights from different airlines can open up more route and schedule options.

What are connecting flights with different airlines?

A connecting journey means taking two or more flights to reach your final destination.

In some cases, all flights are operated by the same airline or by airlines that have an interline or codeshare agreement.

In other cases, your journey may combine flights from different airlines that do not have a traditional partnership with each other.

For example:

Bangkok → Ho Chi Minh City → Phnom Penh

The first flight could be operated by one airline, while the second flight is operated by another.

This type of itinerary can provide additional travel options when there is no suitable direct flight or when the schedules of a single airline do not meet your travel needs.

Why combine flights from different airlines?

More route options

Not every destination has a convenient direct flight.

By combining different airlines, you may be able to reach destinations that would otherwise require a longer or less convenient itinerary.

This can be particularly useful when travelling between smaller cities or regional destinations in Thailand and Southeast Asia.

More departure times

Using multiple airlines gives you access to a wider range of flight schedules.

Instead of being limited to the timetable of one airline, you can compare different combinations and choose an itinerary that better suits your travel plans.

Potentially lower fares

In some cases, combining flights from different airlines may cost less than booking the entire journey with one airline.

However, the cheapest option is not always the most convenient. Travellers should also consider baggage rules, connection times and whether a self-transfer is required.

What is a self-transfer flight?

This is one of the most important things to understand when booking connecting flights with different airlines.

If the airlines do not have an interline agreement, your flights may be issued as separate tickets.

This is commonly known as a self-transfer connection.

Depending on your itinerary, you may need to:

• Collect your checked baggage after the first flight.

• Pass through immigration and customs where required.

• Transfer to another terminal.

• Check in again with the next airline.

• Drop off your baggage again.

• Pass through security and immigration before your next flight.

For this reason, you should allow sufficient time between flights.

Will my baggage be checked through to my final destination?

Not always.

If your flights are on separate tickets or operated by airlines without a baggage agreement, your checked baggage may only be tagged to the destination shown on your first ticket.

You may therefore need to collect your baggage at the connecting airport and check it in again for your next flight.

Baggage allowances can also be different for each airline.

Before travelling, check the baggage allowance for each individual flight, including checked baggage, cabin baggage, weight limits and additional baggage charges.

What happens if my first flight is delayed?

This is another important difference between traditional connecting tickets and self-transfer itineraries.

When flights are issued separately, the next airline may not be responsible if a delay on your first flight causes you to miss your second flight.

Depending on the fare conditions, you may need to purchase a new ticket.

For this reason, when choosing a multi-airline itinerary, don't look at price alone. Make sure the connection provides enough time for baggage collection, immigration, terminal changes and check-in for the next flight.

Do I need a visa for a self-transfer?

Possibly.

Some self-transfer connections require passengers to enter the country in order to collect baggage and check in again.

This means that transit or entry visa requirements may be different from those of a normal airside connection.

Visa and immigration requirements depend on your nationality, passport, connecting airport and destination.

Passengers should always check the applicable entry and transit requirements before booking.

Book multi-airline journeys with confidence

Combining flights from different airlines can give you more routes, more schedule choices and potentially better fares.

But a multi-airline itinerary can work differently from a traditional connecting ticket.

At ThaiFlightCenter, our goal is to help travellers understand their flight options and the important conditions of their journey before they travel.

When your itinerary includes separate tickets or a self-transfer connection, make sure you understand the baggage, check-in, immigration and connection requirements before departure.
