I had a flight last Friday @ 7:30am. It was pretty crowded - long lines everywhere. I left early and took an Uber but there was an accident so it took 50 min to get there instead of 15. The line at curbside was long and slow - by the time it was my turn, they said I was 3 min past cutoff and wasn’t allowed to check in my luggage.

Take Uber. But check for traffic beforehand to avoid this mishap I experienced.
