Do you believe aliens have actually visited earth?

If margins are low how can profits be large?

I think the doctors that determined op was faking it were worse than useless.

I do not believe for a second that checking in early and boarding last makes any difference. It is almost entirely about points, the traveling alone and the meal thing might help but only if you already have the points. I have seen plenty of flights with empty first class seats, they don't upgrade non frequent fliers if the flight isn't over booked they will just leave the seat empty if there are no frequent fliers on board.

Your best bet is to start with as light a roast as you can find. Do not try to brew your coffee weaker to avoid bitterness, this is counter productive. You should brew it at the stronger recommended ratio and then you can dilute with hot water to the strength you prefer, I know it sounds counter intuitive but it produces a sweeter cup as the sweater elements in coffee don't extract as quickly as the bitter. Finally add cream, even a tiny bit tends to mute the bitter flavors.
