The US Travel Association said the country must update its airports and visa system or risk endangering a "golden age" of travel spurred by major sporting events.
A new report, A Vision for a World-Class Travel System in America, predicts “Thanksgiving-like travel extremes” at US airports for 50 days next year, doubling to 100 days in 2028 due to sporting events.
It says the country’s current air travel system is “not built” to handle surges of travellers.
Next year sees the World Cup straddling the date of the 250th anniversary of the signing of the Declaration of Independence on 4 July. The US also hosts golf’s Ryder Cup in September.
