Basically United will be Spirit Airlines but more expensive?

United Continental will become the first major U.S. airline to limit low-fare customers to one carry-on bag that fits under a seat, and it will defer dozens of aircraft deliveries from Boeing in an array of initiatives to boost profit, the company said on Tuesday.
The announcement may frustrate flyers who already feel burdened with travel restrictions and fees from airlines.
United said customers who buy its cheapest fares will not be assigned seats until the day of departure, meaning people on the same ticket may be split apart. United will also prohibit these travelers from carrying on bags that can only fit in overhead bins, and they will not accrue miles toward elite status.
