About waiting lines at the Cathedral of Santiago:
Today is Sunday which, together with Saturday and in particular Friday, is one of the busiest days of the week. I had another look at the webcams. Same as on other days: During the time of the midday mass (12:00-13:00), waiting lines appear with people waiting for entry through the Holy Door on Praza da Quintana and through the main portal on Praza das Praterias. As soon as mass is over and the congregation is filing out of the Cathedral, the security guards remove the barriers and these waiting lines start moving, and they have dissolved within 30-40 minutes.
BTW, judging by the Pilgrims Office's published daily data, June 2022 is a busy month (busier than June 2019 was) but it is not as busy as August 2019 was. And of course, the majority of arrivals are people on fairly short caminos (1 or 2 weeks in total) which is reflected in arrival numbers peaking on the weekend Fri-Sun.
Occasionally, they announce who sponsored the flight of the Botafumeiro. It is usually a parish group or an association from a town in Spain or in Portugal, sometimes even a family, or today a (alumni?) group from the University of San Diego in the USA. These groups can participate in special ways, be it that their accompanying priest is a co-celebrant or that members of the group contribute to the liturgy by singing in a choir or as soloists.
