Thank you for all the advise and ideas. I have a bunch of points and have purchased my limit for 2013. I'm trying to get points for a round trip from SAC to FBG. That's 3 zones each way! Also, since my granddaughter will be with me, I'd like to have a roomette all lthe way. So that will take a lot of points!
I'm thinking maybe my MIL could buy coach tickets for us, then I could call Amtrak and pay for roomette upgrades using my points. Would that work?
Ok, first as noted by Traveler, the sleeper already includes the coach or rail fare tickets. So you wouldn't want to buy coach tickets and then upgrade them. There would be no point, other than being wasteful.
Now, do you have enough points for a one way trip? 3 Zones in a roomette would require 35,000 points.
And then, does your MIL have enough for a one way trip yet?
Finally, between the two of you, do you have enough points combined to get to the 70K you'd need for a round trip?
If the answer to the first two questions is yes, then you book one way and your MIL books you guys for the other way. She does not need to be traveling with you to book you guys into a room, she just needs names and the age of the granddaughter if under 16.
If the answer to one of the first two is no, but you can say yes to the third question, then look at who has the most points that gets closest to the 35K. Then transfer from the other account. So for example, if your MIL has 25K and you have 10K to spare after you use up 35K for one direction, then you should transfer that 10K to her. The idea here is to transfer the least amount of points, since you must pay a penny a point to transfer. So you don't want to transfer 25K and pay for that, when you can transfer 10K and pay less and still have your MIL book the trip for you with her points coupled with a few from you.
Now, if you don't have 70K between the two of you, then you're not taking this trip on points at all. Also remember, that MIL can buy 10K this year if need be or you can buy & gift her 10K this year (can't do both it's one or the other) and that could get you to your goal of 70K. Failing that, you'll have to wait until you collect enough points or pay for the room in one direction, or consider coach in one direction.
