You only get what you fly so the month you dont fly you do not get anything...... Let me explain you how it works............
Company calculate the flying allowance from 15th to 14th of next month, e.g you flew in April the whole month and went on leave in May and flew again in June.
Now your salary for the month of May will have the flying allowance of 15th March to 14th April and salary of June will have the flying allowance of 15th April to 14th May and so on. So basically it does not affect the salary much even when you are on leave.
Yes the company accommodations are fully furnished with all the amenities i.e AC, Fridge, Electric Oven, Furniture and all utilities paid. But remember the utility allowance is only 300 so if the electricity and water bill is more they will deduct it from the salary.Electricity and water comes under one deptt and its not expensive and so is the telephone.Local calls are fixed so they deduct 65 riyals monthly regardless of the calls and if you have an ADSL then extra of 200 riyals and international calls are reasonable now and charge as per the usage. People generally use SKYPE or Other VOiP programs for international calls.
