You should still set airplane mode when airborne for other reasons besides interference with the aircraft. For one, you'll save your battery. It takes a lot of "juice" for your device to search for cell towers that are likely out of reach. You may also want to avoid connecting to a tower outside where you have coverage. E.g. for a flight from Anchorage to Minneapolis, maybe you don't want to connect to Canadian cell towers and potentially receive charges in another country. Obviously this depends on your plan limits. But, yeah, it's not really about protecting the airplane, in most cases

I thought another reason was to avoid blasting everyone* you pass with your phone's maximum power signal while trying to reconnect.

Edit: the problem being interference, not any health effects. I read that the effectively one-way signals from the sky worked somewhat like a jammer.

Microwave radiation from phones doesn't pose any danger. The amount of energy that's transmitted is completely negligible.

Cell phone radiation is negligible

I don't think even the combined power of all the phones in the plane would be enough to cause interference for anyone

The phone's modem is not powerful enough, it takes a couple watts at most, which is tiiny compared to what a cell tower can output
