A group of early arrivals to the boarding gate where I’m waiting for my flight have just broken into ‘happy birthday’ and the rest of us have joined in. 😉
Can’t see that happening in Australia.
That said, this is a small airport and a small aircraft with only a 35-minute flight to Chicago. So there aren’t many of us here, and we just heard about another flight (different airline) being cancelled (mechanical issues?) and so many of those waiting were discussing what they’d do if ours was cancelled.
