The Man Who Pays His Way

Q. I am travelling to South America via Miami. On the way out I just change planes there, but coming back I will be stopping off for a couple of days. I registered for an Esta for the way back, with my inbound dates, but someone said I need it for outbound journey too - even though I'm not leaving the airport. Is that the case? I tried to buy a second one to cover me but it just wouldn't go through.

Q. I have written to BA trying to claim for a delay in November 2006 from Gatwick to Madeira. They have written back to say as flight was more than 6 years ago I am now "out of time for pursuing a compensation claim". But I understood the EU ruling related to flights back to February 2005?
