Only four European teams competed in the first World Cup in Uruguay in 1930: France, Romania, Belgium & Yugoslavia And they travelled there together on the same ship.
King Carol of Romania personally paid for his players, who travelled in the third class section (luckily there were no iceburgs or they may not have got the lifeboats!)
Only the French team travelled first class, only joining players from the other nations to train on the ship's deck.
There is no mention of how the WAGS (wives & girlfriends) travelling - I can't see the modern ones accepting third class tickets, somehow.
