I'll most likely be there at the WC about an hour or so before hand - possibly even earlier as a coworker will be flying out around 3PM & I may just take her to the airport & get her into the WC. It'll be good to finally meet you!
Hopefully the upgrades will process tonight - I'm not too concerned about DCA-MEM because I'm in an exit row, however, MEM-LAS is not a flight I want to be in Y for!
