Group 1 - Gold, Club Europe
Group 2 - Silver, possibly Bronze here or with Group 3
Group 3 - Customers who have paid for a second (larger) cabin bag for the overhead locker
Group 4 - Customers who only have an under seat baggage allowance
Can you imagine the DYKWIA ing that would happen in Group 2... Bronzes (trying to) fight through a crowd of Silvers (The OW sweet spot) declaring "I'm group 2, I have priority", would be a great content uplift for the DYKWIA thread on here!!
