I’ve never found a problem because Just You do provide the clearly identified luggage tags. There is always a designated person watching out for Just You travellers in the check in area of the airport, who will tick you off the list, prior to checking in, I have met other party members doing the same, then checked in and gone through security. The group does get to meet at the departure gate, and if the tour manager isn’t travelling with the group, there will be a designated member of staff to meet and greet you at the destination airport, who will be holding up a Just You sign. The party will all be at the carousel together collecting luggage. Don’t worry, you will be able to find the group at the other side. I’ve done lots of Just You holidays and never had a problem.
