July Fourth travel sees unprecedented airport crowds amid massive flight disruptions

AAA predicts an increase in Fourth of July flyers this year by approximately 1.4% compared to last year's record-setting numbers. United Airlines expects to serve around 6 million passengers between June 27 and July 7, averaging about 4,800 flights per day.

However, the holiday week has not started smoothly due to an American Airlines computer glitch and severe weather conditions leading to over 4,000 flight cancellations across the U.S., as reported by FlightAware.

Storms affected major East Coast cities on Tuesday, with ground stops implemented at key hubs like Newark Liberty International Airport (EWR) and LaGuardia Airport (LGA). More than a quarter of departures were canceled at LGA on Tuesday alone.

Travelers are advised to use airline apps for rebooking when faced with delays or cancellations. Keeping receipts for potential reimbursements through credit card travel insurance is recommended if stranded due to bad weather. Additionally, carrying luggage onboard can help avoid separation from belongings during unexpected changes or tight connections.

Under U.S. Department of Transportation policy, travelers whose flights are canceled or significantly delayed can receive full refunds if they choose not to proceed with their trips.
