GOURMET15
Found this at HUKD and from the comments, seems to be a ripper deal. New Zealand has one qualifying lounge at Auckland airport, and hundreds more overseas. As some have said in the comments, £15 is enough for maybe two drinks, so considering all the goodies you get in these lounges, this is a nice bargain for travellers. Apply coupon GOURMET15 at checkout. Certificate is sent electronically to your email address. Enjoy :)
This is a nice deal, though discovered there's limited options in LAX - wrong terminal! And i don't like my chances of terminal hopping without some TSA agent screaming their head off.
Wish i could use it!
