Checking out the HfP article - kinda reminds me of those "pods" in open plan offices that were all the pre-Covid rage as they helped provide some privacy and muffled noise. Hmmm.
We are heavily considering Finnair to the US in May on their A350/330 fleet to ORD and from LAX so I wonder the likelihood of ending up on one of the refurbed aircraft. And no more cool glassware?! Errgggh - wonder if they will notice if I perhaps drop one in my carryon? :P
