Icelandair offers only true "time-traveling" transatlantic flight for winter 2025/2026

On most occasions, flight FI697 is scheduled to depart Keflavik at 17:15 and arrive in Vancouver at 17:05 local time, arriving ten minutes before its scheduled departure. This occurs because the flight's block time is 7 hours and 50 minutes, while the time zone difference is eight hours. On three dates—December 20, December 27, and January 3—the flight will arrive twenty minutes before it leaves, with a schedule of 17:50 departure and 17:30 arrival.

Another notable example involves Icelandair's daily winter service from Keflavik to Seattle. The most common schedule for this route is a departure at 17:00 and an arrival at 17:00 local time, meaning the block time matches the time zone change. The Airbus A321LR will mainly serve this route, with occasional use of the Boeing 737 MAX 8 and Boeing 757-200.

Other Icelandair routes come close but do not meet the "time-traveling" criteria. For example, flights from Keflavik to Portland depart at 16:50 and arrive at 17:00, while flights to Minneapolis depart at 16:45 and arrive at 17:25.

Looking beyond Iceland, several mainland European airports have flights that arrive shortly after they depart. Most of these are operated by KLM, with examples including Amsterdam to Calgary (12:40-13:40), Edmonton (14:10-15:10), Portland (10:25-11:25), and Vancouver (13:10-14:10). However, none meet the maximum one-hour difference required for inclusion as a "time-traveling" flight.

The closest non-Icelandic entry is Air France's service from Paris Charles de Gaulle to Vancouver, operated by an Airbus A350-900. These flights usually depart at 10:20 and arrive at 11:25 local time during the winter season.

There are no other non-Icelandic long-haul transatlantic passenger markets that meet the one-hour or less difference between departure and arrival times this winter.
