Not sure if it is of any interest - I discovered that Priority Pass has a good offer at present if you follow its link from this page (the Freddie Awards):

http://www.freddieawards.com/

offering 15% off and 15 months for the price of 12. Depending on where you fly from & to and how many times a year, this may be worth considering, especially if you use a number of different airlines in different alliances.

You can also get a further $25 of vouchers if you are recommended by a member - feel free to PM me if you wish.

Probably worth checking out their website & checking whether there are accessible lounges where you plan to fly.

Best regards,
