I just want to ask about graduity and the ticket...

The UAE labor law has stipulated that a worker who terminates an employment contract legally has the right to obtain end-of-service indemnity.
It is the indemnity that is calculated by twenty-one days' wages for each of the first five years, and one month's salary for each year exceeding that, and it is calculated on the last basic salary after excluding all allowances such as accommodation allowance or children's education allowance.
You are also entitled to the value of airline tickets for returning to your country after the end of the employment contract
If the employer violated, you may file a complaint at the Ministry of Human Resources and Emiratisation.
Here are the texts of the UAE Labor Law related to your inquiry:
