American Airlines is coming under fire for fitting their 737 range with ludicrously small toilets.

Ignoring complaints from both passengers and flight attendants alike, the latest range of Boeing 737-MAX airplanes are equipped with restrooms just 24 inches wide: far too small and confined for most adult human beings.

While the new 737-MAX airplanes have been entering service and garnering complaints since November 2017, older (and identically sized) 737 models are being retrofitted with the new loos.

Passenger capacity on the new 737-MAX models is an uncomfortably cosy 172, while the older models had a positively comfortable 160 seats. The older planes are being retrofitted to accommodate 172 seats thanks to the micro-restrooms, as both models are exactly the same size on the inside.

The new configuration is causing headaches for flight attendants and passengers alike, with people unable to turn around or getting stuck inside. If you can manage to use the miniscule facility, the miserly proportioned handbasin is only big enough to wash one hand at a time, and flight attendants are forced to bear the brunt of angry passengers flopping back out into the aisles.
