@deee_onz: We only checked If we needed visas which we don’t but totally missed the ESTA ! You will not be allowed to continue or in our case START our travels without that ESTA approval. You can apply online, the timeframe is 20mins - 72hours for it to be accepted Don’t be like us and not research properly where we had to apply at the airport and countdown the minutes till check in closed But glad we got there in the end
