Abstract : We consider a last-passage directed percolation model in $Z +^2$, with i.i.d. weights whose common distribution has a finite $2+p$th moment. We study the fluctuations of the passage time from the origin to the point $n,n^a$. We show that, for suitable $a$ depending on $p$, this quantity, appropriately scaled, converges in distribution as $n\to\infty$ to the Tracy-Widom distribution, irrespective of the underlying weight distribution. The argument uses a coupling to a Brownian directed percolation problem and the strong approximation of Komlós, Major and Tusnàdy.
