What don't you believe? If it's the statement that they're looking into luggage fees, I'll find a link for you.
Also, note how other airlines who are nickel'n'diming for bags (UAL, COA, DAL, FFT, AAL, etc.) are all in a world of hurt.
The complete opposite, actually. The luggage fees have been a huge revenue booster. Continental is close to profitability and United got there quite a while ago. I haven't really been following the others, though their stocks have all performed extremely well as of late. Yeah, it's not the best indicator considering that they were undervalued for some time, but outlooks are pretty good right now.
As for Frontier and Midwest, they failed for other reasons. Midwest has been struggling for a long time, probably since around 2005 before fuel prices spiked to $150 and these new fees came into play. YX was more or less a virtual airline once they started dropping the 717s as they didn't have their own aircraft or crews. Republic was doing all of their flying, so it was a natural fit for RJET to purchase YX. F9 went under after a recent history of poor management and the inability to garner people traveling on full fares. Again, problems that started long before the fees.
Skybus failed due to complete idiocy. They didn't really have the time to build up a frequent flyer base, and also had to pay for a brand-new airbus fleet, which is ridiculously expensive for a start-up. People that flew with them knew what they were getting into, and the group to which they catered tended to like their pricing structure. And, to make matters worse, they started right as oil prices began the rise up to their peak in 2008. They couldn't sustain operations with increasing variable costs when their fixed costs were set way to high for a new carrier with little investment funding. If I understand correctly, Hodge just thought that it would be a neat experiment and didn't have full confidence in the endeavor himself.
Not true. I live in Chicago and it's great.
While I do agree that service in Chicago and hub cities is pretty good with schedule options and whatnot, elsewhere the schedules are terrible. We only have a single rail line in Indianapolis so I don't use it much as the eastbound comes in at midnight and the westbound is at about 4:45 in the morning. 5.5 hours for a 175 mile trip to Chicago, no thanks.
High-speed rail, if it develops in Chicago, could potentially work very well. But there are many spots in the network that could have a large marketshare were they to offer reasonable timing right now. Granted, it's not too easy to reschedule times that trains arrive at a given spoke, but improvement is needed to get people to use it. Hopefully it's coming soon.
