Heathrow has announced bag drop desks are now open, after the airport experienced an issue with its baggage systems, warning customers may have to travel without their bags.
In an update online this morning, the airport said: "Further to the baggage issues we experienced earlier this morning, bag drop desks are now open and operating normally in Terminals 3 and 5. Terminals 2 and 4 were unaffected by the issue."
Heathrow is continuing to monitor the situation and said passengers who have already departed on flights without their baggage should contact their airlines for further updates.

The airport had been advising passengers travelling today to pack essential items in their hand luggage, saying engineers were working to fix the issue.
Passengers reported long queues forming this morning:

Increasingly typical @british_airways c*ck up at Heathrow T5. Luggage system down, massive queues and, worst of all, no information.— jodeapakosbriggs (@jodeap) June 15, 2017
It comes after rival Gatwick reported similar trouble over the last May bank holiday weekend, when it had baggage system troubles and told passengers some would be flying without their bags too. That was reported just after 5.30am on Friday 26 May and the airport tweeted it had been fixed at 10.51am, though queues remained afterwards.
And both London airports also suffered huge disruption over the bank holiday due to British Airways' IT meltdown, which forced the airline to cancel all flights from both Heathrow and Gatwick over the weekend.
It meant travel chaos for 75,000 passengers after BA flights from Heathrow and Gatwick were cancelled.
British Airways owner IAG is holding its annual general meeting today where it is likely to face questions over the incident, which analysts have said will leave the carrier with a sky-high bill.
Heathrow said on Twitter today that its troubles were nothing to do with IT; the trouble was due to the baggage system failing.
