What is the ruling on selling airline tickets that include a forbidden insurance tax, and airline tickets for airlines that serve alcohol and show movies? Is this considered participation in sin?

Commercial insurance in all its forms is prohibited due to its inclusion of gharar (excessive uncertainty), riba (interest/usury), jahalah (ignorance regarding the subject matter), and gambling. Selling airline tickets whose price includes an insurance tax is permissible, because the tax is ancillary to the sale and is obligatory. However, selling airline tickets for companies that serve alcohol on their flights is impermissible, as it involves assisting in sin, based on the Almighty's saying: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression). The obligation is to limit oneself to selling tickets for airlines that do not serve alcohol. If this is not possible, then the seller's specialization within the agency should be selling tickets for these airlines. And whoever abandons something for the sake of Allah, Allah will compensate him with something better, based on the Almighty's saying: (And whoever fears Allah – He will make for him a way out And will provide for him from where he does not expect. And whoever relies upon Allah – then He is sufficient for him).
