If I'm not mistaken, charter's can cost a pretty penny, anywhere from $100,000-$500,000 and up depending on airlines, aircraft, and distances.
Usually, many teams will demand a certain type of plane. Usually 757 or more likely 767 be sufficient. This is because they sometimes travel with lots of audiovisual equipment and sometimes even their own training equipment. And they like to give the players, coaches, staff, and family(if accompanied) plenty of room to spread out. I know a certain airline that chartered for a certain team one year and for some reason chartered in a 150 seat 727 for 150 players and coaches. That was one unhappy team on the return. It was made clear that from that point on, if that airline expected to charter the team ever again, there would be nothing short of a 757 scheduled. Teams don't like it when people have to be seated in middle seats for a few hours before playing, and when the equipment barely fits in the cargo hold, making it much easier for airline crews to damage it unloading because of the cramped quarters.
Not to mention the food. Those people get enough food on one plane to feed a small third world country. Fresh meals served onboard, a grab bag of food to eat before and just after takeoff, little munchie bags in each seat with goodies inside, fresh fruit available at any time, and all the carb-loaded drinks you can imagine. lol
I believe a team charted a UAL 777 from MCO
for a Bowl game and it ran close to $500,000 for the distance and aircraft, in case that gives you a clue.
I don't have a microwave, but I do have a clock that occasionally cooks shit.
