I agree, this is welcome news for T5. I honestly show up 30 mins prior to a domestic flight because there’s really no reason to show up early. If access is going to be handed out via a premium credit card, I hope the space can accommodate the traffic.
I can imagine the line to get in being like Starbucks at Gate 22 at 8am. I have literally waited there 25 mins when placing my mobile order at the departures curb.
