About to depart

Finally I arrive at the gate. 43min later I will flight to sf. I was quite nervious at the security check, worrying that I may forget sth.
Delta airline’s terminal is quite confusing. I kept figuring out which way to go. And it is too big. The size of one terminal is as big as the whole airport in some other city.
Some elscaters in the airport doesn’t work. It is early. But there is already so many ppl in the security check! What do u build the elscaters for? Now I feel that Guangzhou airport is better in some sense.
