Ryanair has caused quite a stir in the UK - from May next year, passengers will need to check in by smart phone only, meaning they will no longer be able to physically check in at a counter at the airport.

Currently 60 percent of their customers do check in online, but those who don't face a charge of $97 nzd.

For those without smartphones, they will have to find someone who has one. Ryanair does have a policy which lets passengers check-in online 60 days before their flights.

Aviation Commentator Irene King told Jack Tame that it's more convenient to check in online.

He says that it is the future and as a customer himself, the only focus is to get on that aircraft therefore, it is “very sensible” for that company.
