Footage shows the chaos at Don Mueang International Airport in Bangkok, Thailand, today amid the Microsoft global outage.

Long queues formed at the Thai Air Asia counters, with the company saying its 'core reservation and check-in system are impacted by a global IT issue affecting airlines worldwide'.

They added: 'You may experience slower check-ins and longer queues and we are doing our best to address this situation.'

Check-in desks were closed and computers shut down when the tech firm crashed, plunging IT systems around the world into darkness.

The tech giant said: 'We're investigating an issue impacting users' ability to access various Microsoft 365 apps and services. We're working on rerouting the impacted traffic to alternate systems to alleviate impact in a more expedient fashion.'
