what do u mean?
It means that Wizz air and most/all of the low cost carriers don't put people on their payroll just to check people in for flights from Tel Aviv to wherever. Instead, they hire one of the two or three companies that do the ground services on behalf of the airlines.
The same four or five agents will be wearing the Wizz air uniform and do check in and boarding for the flight and an hour later they will put on the EasyJet uniform and do the same for the Easyjet flight. After that they will work the Ryan air flight, etc' etc'.
If your'e not blatantly breaking the rules, they really couldn't care less about collecting ancillary fees since they don't make any more money doing so.
