Air travelers are facing a new reality of higher fees, fewer flights and tough choices about whether a trip is worth the cost. The culprit is volatile oil and jet fuel prices that have been swinging since the war in the Middle East started and fighting near the Strait of Hormuz disrupted global oil shipments. Airlines around the world are responding by trimming schedules and raising fees and fares. Experts say budget carriers and the customers who rely on them will feel the pinch first, but even business travelers and front-cabin passengers won't escape higher costs. Relief may not come quickly even if oil prices start to drop, experts warn, because airlines can take months to adjust fares while they wait for energy markets to stabilize.

Federal investigators say a runway warning system didn't sound an alarm before an Air Canada jet and a fire truck collided at New York's LaGuardia Airport. The head of the National Transportation Safety Board said Tuesday that the system didn't work as intended because the fire truck did not have a transponder. The plane carrying more than 70 people slammed into the fire truck while landing late Sunday night. The two pilots were killed and several passengers were injured. But most were able to escape the mangled aircraft. Investigators don't know yet whether the two people in the fire truck heard the control tower's frantic, last-second warnings to stop before pulling into the plane's path.

An Air Canada jet carrying more than 70 passengers collided with a fire truck while landing at New York's LaGuardia Airport, killing two pilots and injuring several others. Officials say the fire truck was crossing the tarmac late Sunday after being given permission to check on another plane reporting an odor onboard. Before the collision, an air traffic controller can be heard on airport communications frantically telling the fire truck to stop. The crash temporarily shut down LaGuardia — the New York region's third busiest hub — during what was already a messy time at U.S. airports. Transportation Secretary Sean Duffy says LaGuardia is "well-staffed" but still faces a shortage of air traffic controllers.
