Southwest has reverted its limitation on transferring hotel points towards earning the Companion Pass.
Companion Pass seems to the best travel perk out there, and perhaps the only real benefit without hidden charges (except the security fee).
The Points Guy has covered this in detail and so have a few other leading bloggers.
Remember, the easiest way is to target getting the Hotel Stay with Marriott which gives you the required number of Miles to earn Companion Pass.
If you are looking to earn this benefit, now is definitely the time.
