US budget airline JetBlue is experiencing flight delays due to a power outage at its data centre.
The company's website has also gone down due to the issues.
In a statement on Twitter the company said it was experiencing "intermittent network issues" which were affecting airport systems, but it hopes to resolve the problem quickly:

The firm also said its phone system is "sporadic right now".
Flights across the US have been grounded, with many would-be passengers taking to Twitter to voice their complaints:
The travel chaos has not yet had any negative impact on JetBlue's share price, with the stock currently up 0.5 per cent.
