An airline company will never hire cabin crew with visible tattoos. Furthermore, there are companies that completely prohibit the presence of tattoos, no matter what area of the body they are located in. Generally, the policy says that no cabin crew can have visible distinctive mark (tattoos, scars, birthmarks).
If you can remove your tattoo then you will be eligible.
