United said it will increase the price and miles needed to purchase upgrades, effective Oct. 1.
The airline also announced it will strictly adhere to fare rules, including advance purchase and minimum/maximum stay requirements.
United said it will enforce these rules internally as well as throughout the corporate and travel agency community.
The company also will eliminate discounts on sale, promotional and other deeply discounted fares when negotiating contracts with corporate customers.
âThese changes are part of United's overall strategic plan to cut costs wherever possible, while maintaining a product that our customers have told us is important to them,â said Chris Bowers, senior VP-marketing, sales and reservations.
