It is my great pleasure to welcome you to the Airlines Clearing House Annual Meeting in Seattle! This will be my 14th year as secretary-treasurer, and I am proud to say that I feel this meeting has gotten better every year we have held it.

I hope you find this meeting to be as enjoyable and educational as I do, and I look forward to seeing everyone in Seattle.

Warm Regards,
Lori Tully

Local Attractions


At Itsumono, you’ll find a short lineup of seemingly random mashups like tonkatsu tikka masala, loco moco scotch eggs, and miso soup risotto. This gastropub is mukokuseki-themed, which translates to “without nationality,” and explains why there’s biang biang noodle bolognese and scallion pancake birria quesadillas on the same menu.

Meet Korean BBQ

This Capitol Hill Korean BBQ spot is a fantastic place to get some folks together to eat gochujang-marinated kurobuta pork, kalbi short rib, or prime ribeye if you’re feeling particularly luxurious. The best part is that you won’t need to appoint one hard-working friend to do all the cooking and miss out on the fun. Servers operate the tabletop grill for you, which means you can swirl a glass of sake and snack on cheesy corn without worrying if the A5 wagyu is burning.
