While SIN and FRA apparently had more space for customized F check-in solutions, I do think the F check-in/security experience at T5, and bussing to remote stands could be better. For whatever reason there wasn't direct security access to CCR from check-in, it was a lost opportunity. From a long-range planning perspective of a new terminal that will have a 25+ year life I think it would have been a reasonable assumption that the security process is only going to get more intensive. That alone would be a reason to make sure F pax had a dedicated way through security. It would also be nice if there was a dedicated F bus gate below CCR.
