Southwest Airlines will match your elite status from another airline to A-List. With A-list, you may board earlier and earn 25% more points. Even get to hop on an earlier flight.
All you've got to do is provide proof of your status on another airline and your name and Rapid Rewards® number, and Southwest will give you tier status for 90 days. Then just fly three round trips with your new A-List perks, and Southwest will extend that A-List for the next 12 months. Seriously.
