A colleague of mine's daughter worked for American Airlines at Victoria Station check in desk.Having passed several stiff exams she was invited,courtesy of AA, to attend with her entire family the graduation ceremony at Fort Worth Airport, Dallas. My colleague took his aged Mum and Dad,wife and two other daughters. The flights were free and he did not bother with medical insurance.They decided to stay 2 weeks and take in Disney World as well. Aged father had a coronary and was admitted to hospital for several days. My colleague had to leave his father in the States and rush back to the UK where he re-mortgaged his house to pay for his fathers treatment and release from the states.He asked his brother for financial help and got two fingers because he wasn't invited to the freeby. Penny wise.Pound foolish.The US would not let his Dad out the country until payment was settled.
