The Qantas status match ended on the 16th. This was a tricky one to get, since you needed a New Zealand mailing address to take part, but if that was not a problem then you could have obtained a year of British Airways lounge access by matching any existing frequent flyer status you have.
Whilst that deal has gone away, there is another oneworld status match going on.
airberlin is currently matching any non-oneworld frequent flyer status you hold. This was originally a limited time offer until the end of April but the deadline has now disappeared from the application form.
If you have British Airways or Cathay Pacific status then that will not work here. It is a shame that Virgin Atlantic ended their BA status match on March 1st as that would have solved the problem easily.
If the only status card you have is with oneworld, you need to get creative. You need to engineer a match with another oneworld airline and then get airberlin to match you back.
Pull that off and another year of BA lounge access and free seat selection can be yours. airberlin status will also give you benefits when flying with Etihad and potentially with other members of Etihad Airways Partners as well.
