This kind of thing happens and it's happened to me before. So here are some tips, coping strategies, and suggested activities for you, the stranded birding traveler, the next time you find yourself in an airport with a loooooong delay.
1. Calm Blue Ocean. Don't let this unexpected wrinkle rattle you. Say your mantra. Count to 10. Do some yoga breathing. But don't lose your cool because that helps exactly zero percent.
2. Take Action Immediately. Often the first folks trying to re-book are the lucky ones who get a satisfactory result. Find an actual person at the airline's help/service desk. Then...
3. Be Super Nice & Cheerful. The folks at the counter or gate hold you destiny in their hard-working hands. Upset travelers are almost never nice to these professionals, so if you are, they are more likely to empathize with you and help you to solve your travel dilemma.
