swanscn: OK, i have the mask in place and let me know how this option works for you.

As for the BIS, I'm just a few miles short of hitting that 4mm BIS and here's my tip-of-the-hat to you on that achievement. As you know, there's a heck of a lot more people who aren't even close than the rare ones who can claim that milestone. So, you have 5mm BIS on your frequent flyer bucket list? Thank you very much for your support of FlyerTalk.
