We had meetup scheduled in March for a dozen people scattered across the US and Europe. Location was Charlottesville, Virginia. (Sadly, we decided to cancel it.)
We decided it made more sense to prioritise “getting there near the same time” over “cheapest possible”.
Everyone made their own travel arrangements. By picking a central location, it ended up easier / cheaper for some and more complicated / expensive for others. On pound/euro/dollar-cost-average it was fine. (Company paid.)
But that was under old-normal travel logic. In the new normal ¯\_(ツ)_/¯
