Flyers season tickets are not worth the layout if you are not going to go to every game....very rarely do you ever break even if you have to sell unless it is a game vs Rangers Pens or Saturday afternoon. IMHO better off cherry picking games on stubnhub even if means paying more for Pens Rangers etc, Doing the math you will pay more anyway if you have seasons since re-selling the games you won't go to will be for a loss...weeknights are half price cheapie get ins on stub hub
While the gist of your post is spot on... except for prime Games and PostSeason, they certainly do go for a loss on most occasions... a way around that is Partnerships. I personally am involved in a 50/50 split that started at four 25% shares and morphed to what we have now... We have a Select Your Games night and we alternate the odd extra RS Game/extra PS Game on a yearly basis... and work out the perks/gifts as we go.
In this manner the sell-offs are not really that hard to take... and while I attend all my Games except for those I just cannot make, my Partner has go-to guys where he can sell a couple/few Games to each Season at STM Reduced Prices... and we swap Games between the two of us whenever possible when we suddenly have a selected Game that we have conflicts with.
Our Partnership has survived for several decades without much problem... From the Seventies through the Eighties at 25% and 33% and from the Nineties through today at 50%. I suppose we have been blessed and are an exception when it comes to survival... but it is certainly a way to go... for as long as it can work... and please keep in mind that Partners can come in and out as ity has for us before the 50/50 split Era.
As for StubHub Sales... rarely use SH and have at times made a sweet profit when we do -- with prime Games -- and have not yet had to take a loss... but please keep in mind that we attend most Games and use Go-To Guys at STMs Cost whenever we can... If you must sell of many/most Games, this may not be for you.
... And we have all the STM Perks including Events and Gifts and Stored Value when applicable... and have the same Seats for every Game... which, with our Tenure, can be considered excellent for a Mezzanine Location... Jumping on board willy-nilly, unless we are talking expensive Seat Locations, will net you so-so to crummy Seats. It is best to grab decent Seat Locations when available and work you way to better Seats over time.
... That said, with StubHub you can select the Seats you want... just not the same. Best deal may be to join in on an EXISTING Partnership with good Seats, if possible.
