Was told traffic in and out of airport was taking 2-3 hours to get in and out of airport due to new addition. Is this true? Is all traffice just one lane in and out?

My experience was the new airport is very efficient and user friendly.

Can take a while during rush hrs, but nowhere as long as you fear. Went on a monday at five, took me less than 30 mins, but you should have a little buffer. Just in case. But it wont take you more than 45 mins

Absolutely not. Took 25 minutes from New Orleans to the airport.

Not even remotely true. Like 15min tops. 2 lanes in and out
