I wish I had anticipated the delay at the airport and scheduled my ride pickup for 1.5 hours after the estimated arrival time. I was unaware that passengers from Air Canada flights had to board a shuttle bus to access the aircraft.

Make sure you know which terminal to head to upon landing if transferring at Los Angeles as the information board at LAX will show only flight info for the terminal you are at (1 of 8). Transfer information is not transparent from the airline or the airport. Subscribe to airline apps help but can be cumbersome and difficult to manage in a time crunch.

It is great to have a nonstop flight. Might be worth paying a bit extra for it.

Treat this like you’re flying on a greyhound bus. Bring food. Bring a pillow. Bring entertainment. Know that you will be uncomfortable and the airline won’t care.

Get instructions on how to find your connecting flight terminal and gate in LAX. There are no information boards or information desks. We asked a lady in a gift shop, then it was a series of tunnels and stairs that were not well sign posted at all.
