It still works but depends from the time and the terminal. Usually between 9am and 12pm there is no too much traffic coming in. After there is the arrival of the wide body mostly from Europe and there is an increasing of requests.I think instant ping stopped. Dropped off all week. Guess my luck ran out.
Thats what i did today twice and i saw the queue was a bit low so im like wth lemme give it a try since i never waited before.... but i guess i learned my lessonThis is what i do to get insta pings. I drop off. Leave the terminal area and exit at the return to terminals exit and return. Works all the time.
