BBC Trust chairman Sir Michael Lyons ran up expenses totalling more than £12,000 in six months, figures showed today.
Sir Michael, who has "part-time access to a driver and car when working in London on BBC business", spent £875 on taxis.
His expenses, released in a BBC report, cover April to September last year and included £5,593 on hotels, £4,501 on train fares and £427 on flights. They totalled £12,403.
He also accepted tickets to a Seal concert hosted by Radio 2 and took his daughter to see Jack Johnson, also at a Radio 2 concert.
The trust also paid £55 for a single train fare from Birmingham to Euston for his wife on May 10 when she attended the Sony Music Awards with Sir Michael.
He also spent £1,565.75 hosting a box at the BBC Proms for invited guests.
The trust paid out a total of £46,554 to its members in expenses over the period and a further £2,066 to director Nicholas Kroll.
That is 22% less than the previous half-year period.
Other substantial claims were made by Chitra Bharucha, who was paid expenses of £5,350, Alison Hastings, who claimed £6,086 and Jeremy Peat, who claimed £7,354.
Mr Peat's claim included £2,507 on flights to and from his home in Scotland.
Another trust member, Rotha Johnson, claimed £2,255 on flights to and from Belfast.
The lowest claim was made by Richard Ayre who claimed £29.80 on train fares.
More than £3,000 was spent by the trust on hosting boxes for guests at the Proms.
Sir Michael is stepping down from the role in May after four years.
Among the names said to be in the running for the job is former Hong Kong governor Lord Patten.
An independent panel is expected to nominate two preferred candidates, with Culture Secretary Jeremy Hunt choosing Sir Michael's eventual successor.
The cost of Sir Michael's driver came to £13,492 over the six months.
