This past year I didn't plan well enough to get elite status due to flying multiple carriers for work. During 2013, my resolution is to stick to one (or two) for most of my work travel. I would realistically be able to get to the lower status level on either United or Virgin as I'm based out of SFO and they have the most routing from here. I lean toward United (mostly due to international mileage redemption) but their program is so watered down at Silver and I really like the Virgin America flying experience and Terminal 2 in SFO. As an aside, I have a companion pass for 2013 on Southwest with the multiple credit card sign up so I will likely book with them when traveling with my wife. I could try Southwest but it doesn't sound as exciting. I have a trip I need to book for January so I need to decide soon. Any recommendations on which to go for?
