As DA Aquamaster pointed out, make sure that you are well hydrated before you dive. Make sure you're well hydrated in the days leading up to the dive as well.
But otherwise, since you will be at a higher altitude, the nitrogen in your tissues has the potential to be slightly lower than when you are at sea level. This means you will actually be on-gassing at sea level (to get you back to your normally-saturated nitrogen level). You will continue to on-gas as you dive, so having started out with slightly less nitrogen in your body will have negligible affect (i.e. you shouldn't assume you can stay at depth longer just because you started with less nitrogen).
But as long as you are hydrated and prepared for your dive, you could dive as soon as you landed....and you are correct, it doesn't necessarily work the other way (it's a much better bet to hang glide then dive, rather than the other way around).
