London City Airport: Please arrive (at most) 20 min prior to departure
What if we tell you that you could be sitting in a meeting at 5.20pm, reach for your phone as an alert pops up “You have a flight to New York JFK at 6.00pm. Traffic is light: leave now to arrive on time”, grab your suitcase and still make it in time for some duty-free shopping and a quick macchiato before catching your next flight?
