United Airlines is raising checked bag fees starting Friday. The move comes as higher fuel costs ripple through the airline industry. Most travelers flying within the U.S., Mexico, Canada and Latin America will now pay $45 for the first checked bag and $55 for a second. That's $10 more than before the Iran war started Feb. 28. United says it’s their first baggage fee increase in two years. Some customers like loyalty members will still get a free bag. JetBlue also raised fees this week. Airlines say rising crude oil prices are pushing up operating costs. United on Friday also announced a pricing change coming this month for its front cabins. Three new tiers will offer different perks for premium passengers, similar to economy.
