Traditionally, low-cost carriers have been synonymous with straightforward, point-to-point flights. If you wanted to connect between two different flights, you were usually left to navigate the transit process yourself meaning you had to collect your baggage, clear immigration, and check in again for your onward flight. The worst part? These flights were always on separate bookings, so there was no protection if your first flight was cancelled or delayed. You’d simply be left to figure out your missed onward flights on your own (and trust me, as the author, I’ve experienced this — it’s not fabulous!).

This reality made low-cost carriers less viable options for multi-leg regional journeys compared to full-service or legacy airlines, which offer through-checked baggage, smooth transfers without needing to clear immigration, and best of all, cover all flights if a delay to the first causes you to miss the second.

However, AirAsia’s Fly-Thru service has changed this. It provides a seamless, hassle-free connecting flight experience that you would expect — and likely have experienced — from any full-service carrier. But now, it comes with the affordability of a low-cost airline, combined with AirAsia’s network of over 166 destinations across 25 countries.

What is AirAsia Fly-Thru and Why Is It Significant?

Fly-Thru allows passengers to book two AirAsia flights under one booking, with checked-through baggage and no need to clear immigration or collect bags at designated transit hubs.

For example, if you fly from Tokyo to Perth via Kuala Lumpur, your luggage is tagged and transferred straight to Perth. There’s no need to exit the airport, collect bags, or re-check in for your connecting flight — AirAsia handles it all for you.

This enhances travel flexibility and truly turns AirAsia into a genuine regional connector, not just a low-cost point-to-point option.

Sharon Petersen, CEO of AirlineRatings, said, “AirAsia’s Fly-Thru service fills a long-standing gap in low-cost carrier transit travel. While AirAsia has offered a version of this since 2010, it’s now expanded significantly. As a public advisor, I always caution against separate bookings with no protection, so it’s great to see AirAsia address this. The Asia-Australia region has so many amazing destinations that often require connecting flights, and Fly-Thru makes exploring them easier and safer.”

What If I Experience Delays or Cancellations?

This is the part we love the most and it simply wasn’t an option before. Fly-Thru bookings come with the reassurance of protection in case of disruptions. If a delay causes you to miss your connecting flight, AirAsia will rebook you on the next available flight at no extra charge just as you would expect from full-service airlines.

If no suitable Fly-Thru connection is available, you’ll have options such as a full refund or travel credit, providing peace of mind for your journey.
