Just like WN ceo Gary Kelly said "adding fees do not attract customers." I feel people are wising up to the baggage fee nonsense and are choosing southwest or jetblue when possible. I know in phx US has alot of the same nonstop routes that WN does, it makes no sense to fly on US as the price is the same but you get 2 free checked bags on WN.
I'll chime in here for the heck of it....
First off, if you are a "regular" business traveler, the odds are pretty good you aren't paying fees. If you are paying fees, it's the every once-in-a-while oddball trip outside of your carrier network. I know I have to check wine ALL the time....and I've never once paid to check it since the whole fee thing got going....and there's pretty much not an airline I haven't flown.
Therefore....as far as "bag fees" go, right along with what Art is saying, "the leisure travelers going from BOS-SFO once ever 3 years and scoring a ticket for $250 R/T are who those fees are aimed toward. And why not? Consistent with what Art says, "why should one of my twice a month PVD-SFO-PVD trips at $1,000 a pop subsidize someone's $250 trip?
Now, the "Preferred" or "One Pass Elite" customer that scores the $250 R/T? That person isn't paying the baggage fees anyway.
As for WN....I've flown them more than I ever have this year...and US less. But there are different reasons.
With US, I just don't care for the product. I fly US ONLY when necessary or when it's cheap. Hate it that it's that way, I really do...but I've been kicked in the wedding tackle 3 too many times.
As for WN, my reason for flying them more really comes down to (a.) the tickets are fully changeable without the stupid $150 fee and (b.) it's truly a better product.
Lately, especially with the horriffic cliff the economy fell off, my plans have been changing, almost too much. And with WN, I can make the ticket and use the $$$ another time, wihtout the $150. And because of that EXACT reason, I will actually pay a little more, up to $150 more, to fly WN over any legacy carrier.
When it comes to long haul...be it a transcon or TA, I still want a First Class or Business Class cabin....although, these days, even I am struggling to pay for it. And thats where mileage upgrades come in VERY handy.
