I cannot speak for Brian or any other skater, but as I remember from Neil Wilson's competitive days in Belfast....NISA paid for Neil to go to a competiion but his parents had to pay for his coach(es) to accompany him - obviously they didn't get to many of his international competitions themselves as they were not rich, I only remember them at Euros 1997 in Paris - their economy flights were so delayed they missed the warm up for his s/p, but were there for the actual programme!!
Every skater - coach will have their own arrangement, some will pay a per hour fee, others a percentage of earnings, some maybe a mixture of both.
