I was talking to a friend who flies for UA and he was telling me how six months comes so quickly and he was off to get his 6-month flight physical.
He's a 73 FO over the age of 40. I'm at Delta, over 40 and on the A320. At Delta, unless you're in a category with augmented crews (777, 350, 7ER, 330, 764) then you're only required to get a physical once a year. Yes, the Class I expires after 6 months, but the Class II is still good for the rest of the one year period. The only plain text explanation I found on the internet was here. Granted, it's for APA, but it would seem to apply to all of us.
So why does UA require its FOs on non-augmented crews to get a physical every six months?
