yield fare based on distance + fees for buddy passes (since I married the emp, I'm not sure what the price diff is now, but it isn't alot for companion vs buddy, but they are different priority, etc.)

example: CVG/LGA $80ish, BOS/TLV/AMS/BOS $400ish (he got biz both ways) hope that helps

add change fees/excess baggage as needed, rinse and repeat....
