Airplane windshields do not completely block UV-A radiation and therefore are not enough to protect pilots.

Whether it's a flight attendant or a dermatologist, experts agree that travelers should wear sunscreen on flights. In fact, the UV rays on planes are even more intense than when you're back on land.
The study found that spending 56 minutes in the cockpit of a plane at 30,000 feet exposed flight crew members to the same amount of ultraviolet (UV) radiation as spending 20 minutes in a tanning bed.
“Pilots are always exposed to the sun's harmful rays,” says Schweitzer. “We have pretty big windows in our flight deck, and it makes our skin more susceptible to skin cancer. I like to carry sun shields with me, I'll wear efficient sunglasses, and of course, my skin-care routine is major.”
For Checked BagsWhat if you want to bring a whole lot of sunscreen along? Then the TSA recommends passengers put liquid, aerosol, and gel items in checked baggage.
If you react well to taking naps, then you should sleep for a few hours. Or if you find it easy to wake up in the middle of the night and function well, then you might want to sleep for a few hours. But if you find it easy to sleep on a plane, then you might want to stay up and sleep once you are in the air.
The study found that flying in a cockpit for 56.6 minutes at 30,000 feet exposed pilots to the same amount of UV-A radiation as a 20-minute tanning bed session.
According to the TSA, to carry sunscreen inside your cabin bags, it needs to be less than or equal to 100 ml/3.4 oz in volume. It is the same for any other liquid toiletries, such as perfumes and deodorant. This is known as the LAGs (Liquids, Aerosols and Gels) regulation, which was introduced by the TSA.
You will need to limit the volume to equal or less than 100 ml and place them inside a resealable plastic bag. In case travel-friendly containers do not offer you enough sunscreen, it is fine to bring large amounts if you pack them inside your hold luggage. Again, just make sure to carry at most 2 kg/2 L.
