I meant Tier 3 in the general sense, not specific to if we go back to a pre booking system. Under the current system, if someone grabs SDD at opening, gets on it, and there is still SDD available for that evening, no, I don’t think they should be able to book it again. If we go back to prebooking the question is moot because this scenario will never happen.
It absolutely should be allowed. If there are not enough purchasers in the ecosystem to use all of the available inventory those who have purchased should be allowed access to that inventory instead of it just sitting there un-used which is what currently happens.
