Southwest told me that there is an "in between" offer that you will get on your birthday. Right now it seems that southwest is going to be the best program for you because of the great awards they are giving you. No one else can match that.

You don't seem to be interested in status right now and in terms of price, you won't usually find another carrier that can beat southwest (and if they can, it's not by much).

On your birthday, southwest will still likely give you the best program. That along with the cheap flights seems to be the way to go all around for you.

Of course only you can decide what to do...but I would advise you to consider the cheapest flight rather than working a frequent flier program. Us flyertalk nuts usually pay more on our flying to earn miles. Most often our goal is to get elite status...which is not of much value to you right now.
