I think a large issue is due to the fact that since WN doesn't assign seats, and doesn't have a 1st/business cabin, the 'prime' seats for some folks (the first few rows) are being taken by preboarders, while those who are loyal enough, and spend enough to become A-List, or pay the extra $12 for EBCI are out of luck, which is a lot different than the legacies, where money/status/loyalty usually gets you better seats--that's a large part of the frustration.
