Hello everyone. I need some insight from all you LAX FT experts.

I've always had problems getting around LAX when I'm trying to catch connecting flights.

I understand that Delta had relocated to Terminals 2 and 3.

It just so happens that next month I'm flying Delta from YVR to ATL with a 3-hour layover at LAX.

Well, it turns out that my outbound flight from YVR is with Westjet. After all, my reservation states that my Delta flight out of YVR is "Operated by Westjet".

From what I understand, Westjet flights are housed in T2 at LAX. This means that after landing at LAX, I have to transfer over to a Delta connecting flight for my trip to ATL.

Since I'll be switching airlines (my first trip originating in Canada no less) at LAX, I have several concerns.

Will I have to reclaim my checked luggage at LAX before boarding my Delta connecting flight to ATL?

Once I deplane my Westjet flight at LAX, will I have to obtain a separate boarding pass for my Delta connecting flight?

Will I have to travel from T2 to T3 during my layover at LAX? If so, could I make this trip airside? Or will I have to re-clear TSA screening?

I've been having nightmares about my upcoming YVR-LAX-ATL trip. So I could use some expertise.

Thanks everyone.
