With this Qatar airways job.... I assume it is based in Doha.... have you ever been to Doha?? It is rather different to living in the UK to say the least.... hardly the most exciting place on the planet
My point it is might sound glam working for Qatar airways if you have never been/lived in the Middle East but in your late 30s/early 40s moving to somewhere like Doha is not to be taken lightly...
