Booking
Flying EVA Air to London means going the long way around, through Taipei. Total journey time from the US is 22 to 30 hours. That's obviously longer than a direct transatlantic flight, but EVA Air's fares (especially in business class) can be significantly cheaper. And if you want to add a Taipei stopover, this routing turns a London trip into a two-destination itinerary.
Cheapest Months to Travel
January, February, and November have the lowest demand for London flights. These winter months offer significantly cheaper fares, though London weather is cold and grey.
Peak Travel Seasons to Avoid
Summer (June to August) is peak season for London travel, with the highest fares. Christmas and New Year also drive prices up. Spring (April to May) offers a middle ground with better weather and moderate pricing.
Best Time to Book
Book 10 to 14 weeks in advance for the best fares on this routing. Summer travel should be booked 4 to 5 months ahead.
Midweek Advantage
Midweek departures save $100 to $250 on roundtrip fares. Given the longer routing via Taipei, fare savings can be more pronounced than on direct transatlantic flights.
Time Difference to Factor In
London is on GMT (UTC+0) in winter and BST (UTC+1) in summer. That's 5 hours ahead of Eastern Time during winter and 4 hours ahead during British Summer Time. The Taipei-London flight typically arrives in the early morning.
