Travel or not?

I had an argument with my friends about a layup I made yesterday. So, I passed the ball to myself with the backboard and when I received it i was mid air . I made a step when I landed and then I did another two for the layup . I told my friends that the first one didn’t counted cause I was mid air when I received it and that the layup should count , my friends were sure that it was a travel. Who’s right and who’s wrong
