Cabin Crew Career
No, airlines are fine about recruiting people who wear contact lenses or glasses providing these correct your vision to 20/20.
No, many cabin crew members have a family. Whilst working as cabin crew you will receive your working roster for a month allowing you plenty of time to arrange somebody to look after your children whilst you work.
A cabin crew salary normally starts around £14,000 per annum including flight pay. Flight pay is an hourly rate paid to you for every hour you are working away from base.
The majority of airlines do understand that not everybody excels at school, but still have the ability to become cabin crew. If you did not manage to gain a GCSE in maths and English but have gained a higher education or plenty of customer service experience then they will still consider you.
You will be required to live within a certain distance from the airport you are based at. The majority of airlines set a distance of at least a 60 minute travel time radius. This is mainly because you will be rostered on standby which means that you may get called into work at short notice. Apart from this, it is much better to be close to the airport as there is nothing worse then finishing a 10 hour shift to then have to drive a long way home!
Not at all, speaking another language is not essential to becoming cabin crew, although it is desirable.
