Buy Trinity Airways Flights with Alternative Airlines
Rebranded from T'Way Air, Trinity Airways is an upcoming South Korean airline based in Seoul. This airline is currently awaiting approvals from relevant domestic and international authorities before it begins operations.
Trinity Airways was originally founded in 2005 as T'Way Air, South Korea's first low-cost carrier, which is a popular budget option for Korean air travel. With its rebrand announced in 2026, Trinity Airways takes the beloved airline in a new direction, one which focuses the airline on its "vision of becoming a global airline dedicated to customer comfort and reliability". As T'Way Air transitions towards a hybrid airline under Trinity Airways, you can expect access to a larger amount of routes including a growing network of long-haul destinations.
In early 2026 T'Way announced its rebrand into Trinity Airways following T'Way's acquisition by the Daemyung Sono Group (South Korea's largest hospitality company) which own a variety of hotels and resorts. The name "Trinity" comes from the groups vision to bring their airlines, hotels and resorts together as one.

This was my first booking and I used Alternative Airlines twice on this trip. I must say by far the best online booking experience ever.
From start to finish the process of selecting, confirming, processing of payment, timely travel docs, check-in experience was absolutely flawless! I will be using Alternative Airlines every time I travel!
Alternative Airlines made what would have been an otherwise difficult situation much easier to manage. Thank you, Alternative Airlines.
It was my first time using Alternative Airlines and it was one of the best experiences I had in booking my flights. The process was easy and the flight options were clearly laid out.
The support I received was stellar - response time was so quick and I love how they have a WhatsApp option for chatting.
So easy to use and the payment options are very helpful when you need to book a ticket and you may not have the full amount at the moment. Really recommend Alternative Airlines to my clients and friends.
Very easy to use. Helped me to plan my trip to Vancouver and the payment plan made things way easier and stress-free. Would use them again for sure.
I’ve used Alternative Airlines three times already, and each experience has been AWESOME! Their “Buy Now, Pay Later” options are such a game-changer.
My journey with Alternative Airlines was nothing short of excellent. Their commitment to providing a stress-free booking experience and diverse payment solutions has earned them my trust and loyalty.
This was a very simple and affordable way to book such a big trip! I love the way they show you the breakdown of what you are actually paying and your payment schedule. I highly recommend this!
What a great way to be able to see my family back in South Africa. This is made possible since we can buy our tickets and pay it off over 4 months. With the price of flight tickets so high Alternative Airlines has been a literal lifesaver!
I have been using Alternative Airlines for the past 4 years and have never had a poor experience. Destinations are unlimited with a variety of options available for inflight upgrades.
