Why Tim Hortons Coffee Tastes Different on Westjet Flights: the Science of High-Altitude Brews
Q1: Why does regular drip coffee taste terrible on airplanes?
Cabin pressure equivalent to 8,000 feet numbs human taste buds by up to 30%, while humidity under 12% dries nasal passages, dulling aroma perception. Simultaneously, water boils at just 91°C at altitude, resulting in sour, under-extracted coffee from standard grounds.
Q2: When will Tim Hortons Flight Roast debut on WestJet flights?
WestJet begins serving the custom Tim Hortons Flight Roast across its scheduled commercial fleet on November 30, 2026.
Q3: How will the loyalty program integration work between the brands?
The loyalty linkage scheduled for early 2027 will allow members to connect their WestJet Rewards and Tims Rewards profiles. Users will be able to cross-earn and convert loyalty currency across retail purchases and flight bookings.
Q4: Can passengers buy Flight Roast beans in retail grocery stores?
Flight Roast is formulated exclusively for in-flight commercial galley machines and low-pressure environments. Tim Hortons has designated the blend as a WestJet service exclusive, with standard original and dark roast offerings remaining the baseline for ground retail.
