Delta Air Lines is ramping up its 2022 transatlantic flight schedule with 12 restored routes as the surge in air travel continues to spike.

Delta Air Lines has seen a significant increase in international bookings since the US government announced the country's borders would be open to vaccinated travelers on Monday, November 8. According to Delta, in the six weeks since the announcement, the airline has had a 450% spike in bookings compared to the six weeks prior to the announcement.

With the US opening its borders to vaccinated travelers, Delta is expanding its flight schedule with new routes, resumed service, and increased flight frequencies. According to the carrier, Delta is the largest transatlantic airline out of New York's John F. Kennedy International Airport and Boston Logan International Airport and is upping its capacity by 90% by summer 2022 compared to the same time in 2021.
