Ryanair has recently launched a new fleet of planes which includes the Boeing 737 Max aircraft.
Having been announced last year, the new designs offer quieter planes which are much more efficient.
Boeing has received over 4,000 orders for the new aircrafts with Ryanair being the first to fly with them.
Passengers have noticed one flaw with the planes, however, which is that the bathrooms are much smaller than usual.
Flight attendants at American Airlines first reported the problem according to the LA Times.
They complained that there is now only room to wash one hand at a time, as well as causing the problem of water splashing out.
This was echoed by an Air Canada passenger, who took to Twitter to air their grievances surround the smaller basins.
It isn’t the only problem – the back of the plane has also suffered from size issues that has meant when the two doors to the toilets are open, cabin crew members are unable to pass through.
The new planes are able to carry up to 210 passengers, an increase from the Boeing 737-800 planes which could carry 189 passengers.
However, most of the planes won’t fly at the full capacity and will carry 197 passengers.
Thankfully, Ryanair’s leg room will remain at 31 inches, with the seats also staying at 17 inches, despite other versions of the 737 Max’s being less than this to fit in the additional seats.
Other new features include larger overhead bins, holding up to six standard cabin bags, as well as ridding of the in-flight entertainment.
Flights are beginning to phase out screens on the back of the seats on a plane, in favour of streaming services to mobile devices.
According to Dan McKone, managing director and head of travel and transportation practice at consulting firm L.E.K, they come at a steep price.
Not only do they make seats much bulkier, but they can cost as much as $ 10,000 (£7,359).
He explained: “They reduce the weight of the aircraft, and they reduce the expense associated with maintaining that equipment.”
