IHG (formerly priority club) has a new contest which is on from now until the end of 2013. If you stay at holiday inns or related hotels this could be a good way for you to pick up a lot of extra points- up to 86,000 if you get all the goals done. The full details of the contents are on their website here. 

If you do already have elite status on one airline and you're thinking of switching to another you should really checked to see if the new airline has a status match program.

I do this myself recently I had a trip to Singapore planned and the prices on Air Canada were very expensive for the dates I needed to travel so I checked the delta website and they had reasonable fares and also a status match program. You can find info about their program here.

All I had to do was send proof that I am an Air Canada elite member, and they confirmed that if I flew over 16,000 miles in the next three months that I would get gold stars on delta. My trip to Singapore was going to be more than that. 

So I did the status match and the trip, and now I have Delta Gold status in addition to my Air Canada E75K status until the end of February 2014.

I am not sure if I will fly enough on Delta to keep this but I like to have options.
