Group 9 were the last to board, even though they had surrendered their bags and had been told they would be the first to board. My daughter said they were some pretty angry pax at the gate.
But they all got onboard in the end?
Frankly, I envy the proposition at LATAM. Tried them quite a bit around their network, and they have a rather straightforward product. Groups 1-2-3 can bring an extra bag. Groups 4-5, one bag and the other one is tagged. Group 6-onwards, bag gets tagged AND charged (the latter might not always happen in remote outstations). In SCL, they have large team of above-the-wing employees going around the gate with hand-held scanners and printers made by Brock Systems. They tag, print, scan, and even process card payments in seconds. Then they have a person aircraft side to catch all the tagged bags. No one complains, no one says "I was told I could board first", "I always travel with this one and it's fine"... Amazing. And planes get turned around quickly.
