Going away on holiday is always an exciting time, but if you're going somewhere far away, the idea of a long-haul flight can be off-putting.

This is especially true if you haven't forked out for first or business class as there's no option of a comfy bed to lie down on. And it can be even worse if you have children who struggle to get comfortable and sleep on a plane seat.

However, one mum has shared a helpful tip for when you're travelling economy on a long-haul flight that essentially turns your seats into a giant bed - although it's not available on every airline.

The Mirror reports that blogger Adele Barbaro revealed online that during a flight from Melbourne to LA, she paid £104 to provide her youngsters with a proper place to lie down.

By asking the airline for a Sky Couch, she was able to transform her row of three seats into a bed.

Any parents who are planning on flying on Air New Zealand will be glad to hear of this news. Essentially the same as economy seats, the Sky Couch seats come with an extra footrest which can fold upwards to form a bed-like surface.

"If there is two of you travelling, you can purchase a third seat at half price and you will get the entire row to yourself," explained Adele in her Facebook post.

"The leg rests all rise to meet the chair in front and create a completely flat, large play or sleep area. Paul and Harvey had a bed and so did Chloe and I. It’s the next best thing to business (but way cheaper) and perfect for long haul flights with young families. And we all slept."

Other mums who'd used the Sky Couch and were fans of it were quick to comment in agreement. One wrote: "It was just us and one baby – a MUCH better option than the bassinet seats as I could lie down and feed and both me and baby could sleep (while his dad binge-watched movies! Haha!)."

But with it not being available on more airlines, some parents also expressed frustration with one writing: "I wish every airline would allow this as it would be very handy when travelling to Ireland which is two flights first one 14hrs and second one 8hrs but unfortunately they won’t let us use them." The upgrade is currently available on Boeing 777 and 787-9 aircrafts with Air New Zealand, and prices depend on demand, availability and destination.
