This had struck me this morning while I sent my parents off to the airport this morning: mother lined up to check in, me and dad took some of our luggage (i.e the boxes and bags) to be wrapped up. Got back to the line with 4-5 more people to go and got told off by the person behind my mother that "that's not how it works"? Been travelling for quite some time and to be honest, we do this all the time since PROTECTABAG had started service at the airports.
Is this wrong? Should all travelling members stay in line at all times? What should be the lining up etiquette at the airports?
Nothing wrong, because you obviously want to check-in all at the same time. In fact lining up separately would hold people up longer since you will be occupying one desk per person rather than 3-4 people in one go.
