Unfortunately, individual cup holders are not very common on airplanes and I hate having my tray table down because I have so little space to begin with when I fly. The Cup-Pilot provides a stable and safe place to stash your drink without intruding on your space. You can also use it to attach drinks to your suitcase so you can keep your hands free as you navigate the airport. I find this particularly useful because I’m always dropping my water bottle as I try to balance it on my suitcase while boarding a plane.
