I'm a newbie at all of this, so please forgive my ignorance. I'm about to book a trip to Sweden from RDU on United (business travel requires cheapest coach class booking). I noticed that I don't have to join to United's program, but any one of the Star Alliance programs. So I wanted to know what you all thought was best for me. To help out, here's a little bit about myself: I fly mostly for business and that is mostly US and Canada, but an occasional trip to Sweden (Stockholm). I must book cheapest economy fare in Concur or Amex Travel that fits my schedule. It's a suggestion to book layovers if cheaper I have to pay using my corporate card. I mostly want status for me when I travel, but would like to book an occasional free flight (probably international, since we can do SW for domestic) I will originate and end almost all flights at RDU. If you need any extra information, just ask. Thanks.
