I've got an upcoming trip on WN to Vegas and have a question regarding the B concourse security at McCarran. Since WN is now using some B gates and (unless things have improved) the security lines for the C concourse train can get really backed up, is it possible to use B security and hike it via a connector back to C? On another thread someone said there's a hall that connects B to C gates, which of course would make sense if WN is using both concourses. Would this save any time and is C security still as bad as it was back in 2001, which is the last time I used WN thru LAS? Thanks.
