Inevitably it will, though there is no glut of Virgin pilots approaching 60, let alone 65. There are some, but the numbers aren't that significant in the context of the overall seniority list. This (EU) legislation affects all UK airlines, so nowhere will be exempt its ramifications. The almost simultaneous ICAO legislation which effectively prohibits nations from preventing foreign carriers using commanders up to age 65 (for which see a number of topics in R&N) will mean that many more countries are likely to accept aircrew retirement at age 65, so Virgin is hardly unique!
