NEW YORK (AP) -- United Airlines says it will start requiring minimum stays for nearly all domestic flights starting in October. It is also raising its cheapest fares by as much as $90 one-way.

The second-largest U.S. carrier says the moves are among a number of changes it is making to combat record high fuel prices.

Spokeswoman Robin Urbanski says the Chicago-based airline's new lowest available fares range from $69 to $199 one-way, based on length of the flight.

Starting October 6, most United fares will require a one- to three-night or weekend-night minimum stay.
