This is MY DRINK of choice when travelling. It does everything I need to bring me back my sanity (after I've wrangled through strollers, wheelchairs, screaming kids, screaming moms, traffic, chaos, issues, drama, security, et al) at the airport.
Trick: Order your cocktail and a to-go cup of water (with a lid). Enjoy your cocktail at the bar, then order another cocktail. When the bartender isn't looking, fill your to-go cup with your Amaretto Sour and stroll to boarding when your airline calls your name over the intercom!
Have a safe trip! :)
