Curious... by gift boxes do you mean DL is giving these out to pax? Or sending them to certain elites?

Unfortunately I've had domestic flights recently and some DL connection flights coming up so haven't seen the new bubbles yet on board. My next intl D1 isn't until later in April... and that is on AF metal on the way out of BOS so should have good champagne anyway. Return flight is on DL metal so will see whats on there.
