Booking a new flight with another airline wont be feasible since it will cost me twice as much(esp for 4 people) but i wont rule it out. Im just hopeful that maybe one can share an experience of having moved their outbound flight a day early without the change fee and paying for current rates, instead of waiting for the next available flight( a day is ok but 2 will ruin everything).

Alternatives i found so far are flights leaving a day early
