Travellers take note: a minor technical issue in several international air traffic control systems is causing some flight delays across major airports today. Airlines and airports are working hard to get operations back to normal, but if youāre travelling, itās worth checking your flight status before heading to the airport.
If youāre flying today, the best advice is simple: arrive at the airport with plenty of time, check your airlineās app for the latest updates, and keep a book or playlist handy. A little preparation goes a long way when travel slows down ā and your holiday (or homecoming) will still be waiting on the other side.
While no flights have been cancelled as of now, some departures and arrivals are being held back by up to a couple of hours. This isnāt a cause for concern ā the issue is purely logistical and should be resolved as the day progresses. Hereās a live, rolling update of whatās happening at major hubs.
Whatās Causing Todayās Delays?
A minor technical issue in international air traffic control systems is slowing down flight departures at a number of major airports today. The problem, which began overnight, is affecting the sequencing of planes for takeoff and landing ā essentially creating a longer queue in the skies.
Airlines and airport authorities stress that safety has not been compromised at any point, and flights are continuing to operate. However, passengers can expect delays ranging from 30 minutes to over two hours at busier hubs, with some knock-on effects for connecting flights. The issue is being resolved, but it may take much of the day for schedules to return to normal.
Takeaway: Itās a logistical hiccup, not a safety concern ā and the situation is already being worked on.
