Bear with me here, I'm a UA 2P newbie with FT.
Just about ready to book 2 SFO-BOS MRs tagging my daughter along for the ride. This way we each rack up 10.8K miles, qualify for the 5K bonus (neither one of us will be flying in a qualifying class again in March), get the 1K booking bonus and I'll have 2 award tix for my wife and I to vacation in Sydney.
(60K + 10.8K + 5K + 1K = 76.8K) $413.60/76.8K = $0.0054/mile
*GOD, I'm glad I waited for UA to get on board, I almost bit on the same AA deal only to get tickets to places I'm not interested in travelling.*
If depart anytime on Tues - like catching the red-eye out of SFO to avoid a hotel stay in BOS, you can return anytime Wed and qualify for the $203 fare + taxes. We'll spend the day at the aquarium or museum, have lunch and fly back. We're flying 3/2-3 and 3/9-10 in E+ and with the CS25 5% discount, each T class trip will cost $206.80.
Only thorn in my side is that my wife feels like we're 'taking advantage of the system' be doing MRs, and exploiting our daughter by flying her XC twice to get a free ticket... ANY OPINIONS?
