Selling government airline tickets if one travels by land
Question

                Is it permissible to sell government airline tickets that were given to me, because I traveled by land?
Praise be to Allah.there is 
    nothing wrong with selling the tickets if you have no need of them, unless 
    your traveling by land will cause some delay in your work. In that case it 
    would only be permissible for you to travel by the means approved, i.e., by 
    air.
