How do I actually join a train squad in the Labyrinth??

I add myself to the LFG squad and I enter the Labyrinth, but EVERY time all the players are in a different instance. I tried logging out and back and no change. LFG works for me with the Mad King Realm, but how do I do this with the Labyrinth then??

HALP!!

Right click someone else's portrait in the squad UI and select 'Join in Mad King's Labyrinth' from the list that appears.

It might tell you the map is full, in which case you need to either keep trying or choose another squad.

Adding on to Danikat, considerate commanders will lock themselves alone in group 2 in the squad, while everyone else is in group 1. Obviously go to the map with the commander on it.

Also the Mad Lab has a 25 player cap on it..... so squads larger then 22 are usually full maps (counting for a few afkers).
