United Airlines will start enforcing its carry-on baggage size restrictions more strictly. The airline says bags will be more carefully reviewed at the security checkpoint and at gates prior to boarding. Any passengers with carry-on bags that exceed 9 inches by 14 inches by 22 inches will be forced to return to the ticket counter to pay United's $25 checked bag fee. The stricter enforcement prompts speculation that United is trying to collect more revenue through checked bag fees.
