Other airlines also have cramped sits, what little they did better than Spirit isn't worth the price, and the experience was inconsistent: some times you'll get nice flight attendants, a comfy plane, and a good check-in/check-out, other times you didn't. can't plan around them. With Spirit I could plan around exactly how bad my experience would be reliably. Just about any inconvenience was some fee away to address it.
Frontier was the cheap airline that just wasn't worth it. On the flip side, AA was overpriced with snobbish (just my experience, very limited) staff. Because it's a "cheap" airline, Spirit came with low expectations, and it only exceeded them to the most part.
I shop at walmart compared to whole foods and other "better" chains for similar reasons. "great value" as walmart's motto goes, it isn't about the price, it's about the value you get for what you pay for. Spirit was the "great value" airline.
I don't think this effort to buy it will prevail, I only wish the GME betters were in on this action. The airline's value hasn't gone away, similar to Gamestop. The people like it, the demand for it there, the airlines assets and staff haven't lost their value. I don't see how it isn't a good investment. This attempt to buy it is to little, too late. but if it came in actual stock purchase agreements, I'm down for it. But donating random cash to some site as a pledge, I don't know about that.
