I would like to suggest that once a player clicks on lease aircraft, that there be another three minute delay for that particular player to be able to do that again if he/she can't make up their mind. I experienced a hold of 12 minutes because someone couldn't make up their mind. It doesn't take (much) rocket science to know if you can use the plane or not. So my suggestion is once the the 3 minute limit is up, the same player has to wait 3 minutes for the next attempt. If the player loses the chance to secure the aircraft then so be it, if another more decisive player comes in and grabs it. This game is to big to hold on to something that long. Do your business or get off the toilet! One should already have an idea whats needed and it shouldn't take 12 minutes of re-clicking "lease aircraft" to decide and hold up many more decisive players.
Thats why I suggest a delay after the first click on "lease aircraft" on the used aircraft list for that particular player for that particular plane. If you can't decide in 3 minutes, then you should be delayed 3 minutes before you can check on the particular aircraft again. I think some people may agree with me. Ok, got that out of my system. Thank you for letting me vent.
P.S. And yes its only an opinion, but I think its a valid one.
