Hmmm. Kids.
How often does the average FF (GGL) travel with multiple colleagues on a business trip? Suspect not often - so no particular increase in lounge or TFW loading.
However, 3 is the new 2 when it comes to kids so GGL city break, ski weekend, half term, summer holiday, visit farm house in Provence, winter sun breaks etc. will now result in extra kids in GF/TFW.
I predict a burst of “kids behaving badly in the lounge” threads in the near future...
