am i in the wrong?

hi guys i’m M18 and from south africa, i just missed my flight bc i was” late” apparently. Boarding started at 2:34pm and ends at 2:59 pm. how can boarding take 25 minutes?? EWR security was filled, the gate is extremely far too, it isn’t possible to make it to the gate before 2:59pm. and even when it’s 2:59 they ALWAYS wait, from my experiences they have always waited for anyone else. i arrived at 3:00pm and immediately asked the worker for help and miss girl tells me i missed the flight, HELLO WHAT.

while i was talking to the lady, she gave me sm attitude and she could see that i was freaking out bc im alone here, weirdly they didn’t charge me anything but im still pissed off because it’s not possible to make it on time and i was running too.

also last thing i found out is that the aeroplane didn’t leave until 3:27pm, even tho i begged the lady to open for me.

but anyways, definitely my last time flying with united.
