Flying Vs invisibility

I would love to have super Powers but having to choose between flying and invisibility is very hard.
I think I would prefer the power to fly. One of the advantages of this power is that it would let me go very fast from one place to another. Undoubtedly I would be travelling all around the world without spending a single dollar on tickets. And another advantage would be that I could be able to visit my friends more often.
Anyway having only the power to fly would not let me help others much, it is not like being superman, he could fly and he was very strong and he had special rays on his eyes and lot more extrapowers. Se when he flew to stop a train he mange to arrived before the train to the broken bridge but then he was spuerstong and could stop the train and avoid the catastrophe. I could be able to arrive before the train but that would be the only thing that I could do and I would be the first person to watch the catastrophe.
But please do not get me wrong and think that I would not want the power to fly. I would do. But I would love to have a few more superpower so I could be a super hero and help other people otherwise I would be only a superfast traveller.
On the other hand the power to be invisible would be a nice power too but I can’t find much utility having it unless you would want to robe banks and be a supergosip.
Summarizing, having super powers would be very cool but I would love to have more than one. But If I could not have more than one,I would choose flying.
