"NEW YORK – LONDON BOOKINGS OPENING
After just six months connecting New York to Paris, La Compagnie is pleased to announce that bookings for our all-business class flights from New York (EWR) to London (LTN) open next month. Flights to London begin March 29th – you can start booking those flights from early February. Mark your calendars!"
I'd love to try them one day, and I wish this one the best of luck.
