United Airlines has increased its checked baggage fees to $45 per piece for customers in the United States, Mexico, Canada, and Latin America. This increase comes as the Middle East war continues to disrupt global oil supplies, particularly near the Strait of Hormuz where a fifth of the world's oil typically passes. Some customers will still receive a free first checked bag, including co-branded credit card holders, certain loyalty-tier members, active military personnel, and travelers in premium cabins. The average price for a gallon of jet fuel in Chicago, Houston, Los Angeles and New York reached $4.88 on Thursday, up from $2.50 before the conflict began.
