Last week I have been to Portugal for 6 days.
BmiBaby runs convenient connections to Portugal from Birmingham International Airport. I found a return ticket for £85 and I cound not resist it. Departure was 2 o'clock in the afternoon and the return was 22:30 in the night; decent timetable for budget flights.

This is not a place write about Portugal, but I cannot resist mentionning the convenience of living in the city with an international airport!
