Some things I've done to greatly reduce the incidence of bubbles (from air or dust) is to:
1) Go to a small room that is able to remove air, such as a bathroom with ventilation fan.
2) Remove the dust in the place either by wiping it all down with a wet sponge or Swiffer duster.
3) Wash and dry your hands.
4) (optional) Have experience doing this sort of thing (with phones, tablets, etc.), so that aligning it isn't so foreign to your hand-eye coordination.
5) Use a wet screen cleaner on the display and dry it with a microfiber cleaning cloth.
6) Apply it quickly and immediately attempt to squeeze bubbles to the edges of the display area. Something like a credit card can help with this.
7) Let it set for about half an hour.
After that, it should be good to go.
