Airlines in Europe are trying to avoid a repeat of last summer's travel chaos, when strikes and staff shortages were so bad that London's Heathrow Airport capped passenger numbers and asked airlines to limit ticket sales. Travelers are going to jam European airports once again in July and August, with passenger numbers returning to or exceeding pre-pandemic levels. (Photo: Passengers at Lisbon airport)
