He said "amazingly, after a few media inquiries", Jetstar was able to put the school children on an 8.20am flight to Auckland.
"So in the end it all turned out to be an exciting adventure for them. They played for the TV cameras in the terminal, and there we go."
The kids had given an impromptu orchestral performance when television news cameras showed up at the airport.
The children were fine today, he said, but had learned "an important lesson" - "the importance of selling more cupcakes in order to fly Air New Zealand".
Pupils from the school had fundraised for the trip by baking and selling cupcakes and other treats.
Last night, Hooton tweeted that Jetstar had cancelled the trip home for "engineering" reasons.
"There are no hotel rooms in Wellington because of @acdc - not that @Jetstar-NZ has offered them as far as I know," he posted in a series of tweets.
"@Jetstar-NZ says they may be able to fly the kids home on TUESDAY. Their school graduation is on Monday morning."
The budget airline then said it might be able to put the kids on a Sunday night flight, and provided the group with Subway vouchers, Hooton said.
Last night Jetstar spokesman Luke Enright said the flight was cancelled because of an engineering problem.
