They reported 9.9 billion in profit for their third quarter last year, so I think 458 minutes of profit from that quarter.
I assumed 90 days in the quarter, or 129,600 minutes.
So dollar or minute wise, that comes out to a 00.35% penalty to that quarter.
Edit: Which isn’t even close to the 36 minutes in that article, so I’d err on me being the wrong one.
Edit 2: I think I see the difference, I was looking at their profit, not their revenue.
I wouldn’t recommend this if you fly very frequently, but you can take some ibuprofen or acetaminophen at the start of the flight / part way though and it should be active around the time you start getting sore.
