737 Updates - PSU
Changing the little things about travel can make a big difference. The passenger service units (PSU) are one great example. Below are old and new versions on the 737, the new lights are LED and better for reading while using less power and maintenance. The air vents are better too by spreading the air more evenly. Airbus has improved PSU's on the A320 family too.
