Expedia Group reported weaker-than-expected revenue for the first quarter, attributing the shortfall to reduced travel demand in the United States. This led to a decline in Expedia's shares by as much as 12%. The company’s results reflect broader trends in the US travel sector, where spending on flights and lodging has continued to fall, according to Bank of America credit card transaction data. Airlines have also warned of weakening demand for US travel among European tourists. Despite relatively stable spending on everyday services like dining out, larger travel-related expenditures have declined, signaling challenges for the US tourism industry. These developments are expected to impact airlines, hotels, and hiring within the travel and leisure sectors as the summer season approaches.
