Sorry but because my English is bad do you understand from the following message that we can rebook in a future date by just choosing a new date and not paying any fare difference?''We have decided to facilitate rebooking for our clients in a form of waivers which would allow clients with flights scheduled within March 1st to May 31st to reprogram their trips free of any additional charge before February 28th 2021 and complete their flights before February 28th 2021 as long as there is no change in route or service cabin.
