Despite major advances by many cities and battles between Raleigh/Vancouver and Austin/Seattle, London continues its lead to host the Airshow World Tour on Feb 26. We can't predict who will win this round, but we can describe the process.
Once a quorum is reached for a city, we will continue the early registration discount for a grace period of 24 hours. This is to provide a final chance for registrants in mid-process to complete their registration, and backers of other cities to change their allegiances. After the one-day grace period, the 50% early registration discount is removed, and tickets for that city are sold at full price.
In the meanwhile, we will work with our venue sponsors to lock in the specific venue to announce.
