I've only used it once upon arrival and I always do carry on.
How does it work for checked bags?
If I recall, the agent picks you up right at the turn down the ramp to Immigration, then once you clear immigration, you'd have to wait for your bags in baggage claim, correct? So if there's a delay in baggage, time saved at immigration is out the window?

I'm looking at a new CC and one of the airline lounge perks is ClubMobay arrivals/departures as well as checked bags. So just evaluating the convenience if I actually checked a bag to MBJ.
