It'll be interesting to see whether there is any change in the enforcement, or lack thereof, of the size limits on carry on bags and personal items. I find WN to be extremely lax in that area. People shove bags into the overhead bins that are clearly beyond the published size limit. Often, I see people with two carry on size bags, neither of which remotely qualifies as a personal item. Personally, I'm fine with the lack of enforcement, but I know others may disagree.
