Merhaba, Denver!

On June 11, Turkish Airlines finally began its 14th US route: from Istanbul to Denver. Despite being disclosed as a future destination in 2021, Turkish Airlines did not officially announce service to the Colorado city until April 2024. The first flight came barely two months later, meaning little lead time to increase awareness and bookings on the route between two Star Alliance hubs.

The first roundtrip deployed the 349-seat 777-300ER. The carrier often initially uses the 777 on brand-new long-haul routes to accommodate dignitaries, journalists, and others. The type will also be flown on June 13. After that, the route – now Denver’s longest – will exclusively use the 316-seat A350-900.

In 2023, Denver had approximately 245,000 passengers (336 passengers daily each way) who traveled to Turkish Airlines’ core geographic markets from the US: the Middle East, parts of Central and Eastern Europe, parts of Africa, Central Asia, and South Asia.

Tel Aviv, Kathmandu, Johannesburg, Dubai, Delhi, and Addis Ababa were the most popular origin-destinations. Turkish Airlines serves them all, although the war means that Tel Aviv flights remain suspended.

Emirates, Qatar Airways, and Etihad do not fly to Denver. Interestingly, Ethiopian Airlines’ Chief Commercial Officer told me in November that Denver will be a future destination in its network. We must wait to see if this materializes. If it does, Addis Ababa will become Denver’s longest route.
