(Not European, but definitely time travel…)
Someone I worked with in the Antarctic managed to do a ~12 hour flight in a Twin Otter (including refuel stops) and still arrive the day before he departed.
South Pole station works on New Zealand time, which in summer is UTC+13, and the British base at Rothera on the Antarctic Peninsula works on Falklands time (UTC-3), so there is a 16 hour difference between the two.
He left South Pole early in their morning, and arrived at Rothera late evening on the previous date.
