Singapore Airlines customers can now connect to 120 US cities that the airline does not fly to directly. These cities include Knoxville, Tennessee, and Anchorage, Alaska. Southwest Airlines started flying to these cities in 2026.

Travelers from Vietnam and Southeast Asia can benefit from this deal. Singapore Airlines flies from Ho Chi Minh City and Hanoi to Singapore every day. Its budget airline, Scoot, also flies to other cities in the region. Now, passengers can fly from Vietnam to the US with just one ticket.

This new deal is called an interline partnership. It lets travelers book flights on two airlines with just one ticket. They can check in once and their bags will be sent to their final destination.

A Singapore Airlines plane was on display at the Singapore Airshow in 2022. This shows the airline's presence in the region.

This deal is part of a bigger trend. Many Asian airlines are partnering with Southwest to reach US cities they cannot fly to directly.

Before, travelers had to go through a lot of hassle to get to smaller US cities. They had to clear immigration, collect their bags, and buy another ticket. Now, they can do it all with one ticket.

Travelers can buy these combined tickets from Singapore Airlines, travel agents, or travel websites. However, they cannot buy them from Southwest's website.

Southwest's Chief Operating Officer, Andrew Watterson, said that Singapore Airlines is the eighth airline to partner with them. This partnership will help Southwest reach more international travelers.

This deal is a big change for Southwest. The airline used to only fly within the US and did not partner with other airlines.

Singapore Airlines is a highly-rated airline. It was ranked the second-best airline in the world in 2025. It also has the best cabin crew, first class, and is the best airline in Asia.

Singapore Airlines flies to many destinations around the world. It has a budget airline called Scoot and is based at Changi Airport, which is one of the best airports in the world.

The Singapore Airlines Group flies to over 130 destinations in 35 countries. It is a big airline with many connections around the world.
