Is cabin crew salary enough to live on in London? Real budget from a BA new joiner

First year BA Heathrow budget, because everyone asks. Take home in a normal month low 2,000s. Room in a shared house in Hounslow 800. Transport and food 400. Phone, bits, 100. That leaves a few hundred, and long haul months with allowances add more. It is tight but it is possible, and it gets better every year. Living centrally on year one pay is not possible, so do not try.
