Noticed some companies are now offering SmartDelay from Collinson, who provide the LoungeKey access that Curve has, including o2 (for a limited time) and Revolut.
Basically, if your flight is delayed by more than an hour and you’ve pre-registered your flight details, you get sent a code for free access to the lounge while you wait.
I found this useful with o2, as I got a free lounge when my flight was delayed. Is this something Curve could look at introducing for Metal/Black cardholders? I miss it!
