Rating Newest Oldest. Best Answer: LAX is a horrible airport. Definitely allow 3 hours before an international flights and a minimum of 1.5 hours for domestic. I've been there and missed flights because the security line gets so long, and the airport is under construction (and has been since the dawn of time).

lax sucks, i would suggest 2 hours at least, I do think that the security opens back up at five am, but could be wrong. Take a book, ipod, computer, or hell a cell phone and wake someone up, text them.
