It's a nightmare scenario that can happen on any trip - the flight is delayed or cancelled. Often, it will involve a lengthy queue along with your fellow passengers to speak to airline staff to discuss options and receive updates. But a clever holidaymaker has shared a hack that cuts out the waiting in line, and is as simple as making a phone call. In a post on Reddit, they urged passengers facing delayed or cancelled flights, 'don’t just wait in the long customer service line at the airport'. The traveller pointed out that most of the time, it will be quicker to get through to a staff member on the phone.
