for carriers operating across the Gulf, with restrictions on shipping adding to broader regional uncertainty.Airlines can therefore make operational changes at short notice depending on developments, meaning a service listed as scheduled can still be subject to delays or cancellation.For passengers, checking the status of the specific flight number is more important than relying on the overall route schedule.DXB gets busierDubai authorities are increasing operational readiness across airport platforms and checkpoints as residents and visitors return from their summer holidays.That means passengers should expect higher traffic through Dubai's airports as the post-summer travel rush gathers pace.Travellers should allow additional time for road traffic, check-in, security and immigration, particularly during busy departure periods.Travel checklistUAE passengers flying today should:Check their specific flight status before leaving home, even if the service was previously confirmed.Arrive at least three hours before departure, or earlier if advised by the airline.Allow four hours when flying from Dubai with flydubai, in line with the airline's guidance.Complete online check-in where available.Allow extra time for traffic, security, check-in and immigration.Keep contact details updated with the airline to receive disruption alerts.Prepare for last-minute changes, including delays, cancellations and schedule changes.Follow official airline and airport channels for the latest information.What to watchFor UAE residents, the key developments to monitor are traffic through the Strait of Hormuz, US-Iran diplomatic developments, further sanctions, oil prices and airline schedules.Any escalation around the strategic waterway could have wider implications for regional shipping and energy markets, while airlines may continue reviewing their operations.For travellers, the most important step remains simple: check your airline and airport status before setting out, as schedules can change at short notice.Dhanusha is a Chief Reporter at Gulf News in Dubai, with her finger firmly on the pulse of UAE, regional, and global aviation.
