"Is this normal or do we have a Fawlty Towers airport?"
The doors finally slid open at 5.20am, five minutes after check-in, and passengers were greeted by the warmth of the foyer and airport staff were able to check in their bags without incident.
Hawke's Bay Airport CEO Stuart Ainslie said the unfortunate incident was a "one off" and was surprised no one had notified the airport staff at the time.
"Because it was frosty the door didn't open right, but when the staff realised they were on it within minutes, so I believe it's just a one-off glitch," he said.
With more than 30 volunteers on deck at the airport to assist passengers, Ainslie said it was surprising that no one had reported it.
"We're doing a regular customer survey and we're really keen to find out what people think about improvements.
"The doors are auto-slide doors, but in this case they got stuck.
"In the scheme of things, these sort of things do happen at airports every day, it's just unfortunate that this particular incident happened on a cold, frosty morning."
Despite the frosty reception, Crooks made it to Auckland on time and spent a week thawing out in Port Douglas.
