Birmingham Airport
Birmingham airport is pretty nice. It is a fairly busy airport with a complete mix of scheduled flights to a fairly large number of worldwide destinations, charter flights, and a few budget flights. Because all of this is in one terminal there is no shortage of shops and cafes.
Getting there by public transport
Birmingham International station at the National Exhibition Centre is connected to the airport by a minute-long transit ride. This is a mainline station with regular trains to London and Birmingham, and less regular trains to as far afield as Edinburgh, Glasgow and Brighton. If you are not going to London, there are trains to the deeply unpleasant Birmingham New Street station every 15 minutes or so, from where you can catch regular trains to every corner of the country.
