United Air to charge obese double on full flights Wed Apr 15, 5:29 pm ET LOS ANGELES (Reuters) – United Airlines, a unit of UAL Corp, will require obese passengers bumped from full flights to purchase two seats on a subsequent flight, matching the policy of some other carriers. The change brings the Chicago-based in line with eight other airlines including Continental, Delta, JetBlue and Southwest, United spokeswoman Robin Urbanski said on Wednesday. "Last year we had 700 complaints from passengers who had to share their seats," she said.
