Article 75 states that an employee shall be given a minimum of two (2) days paid leave every month for period of service of at least six (6) months and a year at most, and thirty (30) days of each year for a period of service exceeding one year.

In Article 76, the employer has given the right determine the start of annual leave and may divide it if necessary to two or more periods. Official holidays specified by law or by agreement, or leave due to sickness shall be deemed part of the annual leave if it falls within the same period as stated in Article 77.  

Providing air ticket to employees is not mandatory and is purely contractual in nature. Meaning, you are not entitled to an air ticket allowance unless agreed upon in the labor contract. 

Though most of the companies in the UAE are giving full salary during annual leave, the labour law (as provided in Article 78) only requires basic salary and housing allowance. If labor contract explicitly states that annual leave salary should include all the regular allowances granted by the employer then the employee is eligible for the full salary.

Moreover, leave salary should be given in addition to  the entire wage due prior to annual leave in accordance with Article 80.

In circumstance where the employee is required to work during his annual leave and the days of work are not carried forward, the employer must pay basic salary for the days of work in addition to leave allowance.
