Some passengers were asked to remain outside the airport terminal upon arrival About 2,000 people at Bristol Airport have been left stranded after a small fire caused a serious power failure. Flights were grounded with some passengers saying the terminal was in darkness when they arrived earlier.
The back-up generators failed after the fire at 03:00 BST, with the airport reporting "significant disruption and delays" at its busiest time of day.
Airport chief executive Robert Sinclair said he hoped the operation systems would be back to normal by mid-morning.
Paul Raymond, who is flying to Spain, said he arrived at 03:10 BST and heard the power had gone off shortly before.
"For a short time they were telling people just to leave the terminal building," he said.
"There was nothing - no computers, no security - nothing is operating at all."
The fire happened in a distribution panel, officials said, and the failure of the airport's back-up generator led to a complete loss of power in the terminal.
Three hours later the power was partially restored.
A major operation is currently in place to clear the backlog of flights which had been grounded.
Power has been partially restored to the terminal building at Bristol Airport Airport chief executive Robert Sinclair said it was a "fluid situation" but he hoped the system would be fully back to normal within two to three hours.
"Clearly I'd like to apologise to all of our passengers that have been caught up in this disruption," he said.
Passenger Alistair Barclay, from Taunton in Somerset, was due to fly to Faro but arrived at 04:30 BST to find he was one of the thousands left stranded.
"It is just one of those things," he said.
"No-one's fault. A fire in the basement apparently so you've got to go with the flow."
