A baggage IT system issue at London’s Heathrow Airport, Europe’s busiest, has forced passengers to travel without their luggage.

The issue occurred roughly around 6:30 a.m. on Thursday, June 15, affecting the airport’s terminals 3 and 5.

Airlines affected included British Airways, American Airlines, Virgin Atlantic, Qantas, Emirates, and Iberia, among others, leaving passengers with no choice other than to pack essential items into their carry-on bags and continue on without their checked luggage.

Though the airport is still determining the exact cause of the issue and the total number of passengers affected, it was resolved by 9 a.m., with airport representatives urging customers who had to fly without their luggage to contact their airlines in order to retrieve their belongings.

The incident occurred just weeks after British Airways experienced an IT failure that left thousands of passengers stranded at London's Heathrow and Gatwick airports.
