Savvy travellers profited from Southwest's 737 Max flight changes

Savvy travellers have taken advantage of Southwest's generous flight-change policy during each Max flight schedule change allowing them to save money and time on multiple Southwest flights. United and American have rebooked affected travellers on other flights for free or allowed them to make changes without penalty during the Max crisis. But Southwest's system has been more liberal, enabling any traveller to change any flight in the covered travel period for a short window (usually a few days) each time Max flight changes were announced. With the fare difference broadly waived each time Max flight changes were announced, travellers changed existing flights to better times, dates or even eligible nearby airports and/or booked cheap new flights and immediately changed them to pricier flights without paying more. <br/>
