Stansted airport in Essex says it is "completely unaffected at the moment" by the air traffic disruption in the South of England.
Thousands of air travellers face delays after air traffic control company Nats experienced "technical problems" at its Hampshire control centre in Swanwick.
The problem led to Nats restricting the number of aircraft flying across the south of England and those taking off from airports.
A Nats spokesman said: "There will be delays, although we are not sure how long they will be."
