you know what i learned from traveling? i learned that the airports in japan and the airports in hawaii are very small and efficient. to get to a far gate in japan, they have trains. and to get to the far gates in hawaii, they have busses. i learned that the airport in argentina is huge and inefficient. i went to the airport 2 hours before my flight and almost missed it. from the long check in line, to the first screening. they scan and check your carry on bags, then the super long line at the immigrations, and once you spend an hour getting pass that, the gate is like 20 minutes away. i couldn’t believe how long i had to walk to my gate. if i ever go through buenos aries airport again, i will be at the airport 3 hours before. and now i’m very thankful for the small and efficient airports in japan and hawaii.
