I am no longer flying on business and therefore have several airlines miles in various accounts. With the use of switching phone cos, signing up and using visa cards and the previously mentioned conversion to hotel points most accounts can be used or brought up to a ticket level.
It seem that the magazine deals are unsolicited and meant to be that way. I have received three. One was magazines for points and could have been of value. The second was magazines for points BUT required payment of $2 per magazine selected. A third offered other items for little points BUT too much money!!!
I do not believe Hilton points are never expire as previously mentioned. The can be cancelled if you do not stay in one, for I believe 3 years.
