At just over 2,500 feet, it's the highest point on the TMT. In spring, look for red currant blooming here. From Tom's Crossing, the West Tiger #2 Trail heads steeply uphill providing another way to reach that summit. Continue down the TMT on many switchbacks and, in about 0.3 mile, note the junction with the K3 Trail.
I rarely show up more than 1.5 ahead of time. Another idea: technically, the ticket counters usually open 24 hrs before your flight, and sometimes this is the only way to easily get special seats like exit rows.
Major airlines allow customers to complete the check-in process online or through mobile phones, typically beginning 24 hours before the flight time. Customers enter flight information and identification information to check in early for their flights. Consider the benefits and check the airline's guidelines to determine if early check-in can be advantageous for you on your next flight.
