I have tent camped and flown. It is possible. As a solo person I brought the following within airline allowances. If there is more than one person it is much easier as your luggage allowance increases with each person.
1 10x10 tent (this is what I slept in)
1 7x7 tent (this is where I stored my gear)
1 10x12 rain/sun shelter
1 folding bag chair
1 folding stool
twin size air mattress
electric pump for air mattress
battery operated coleman lantern
flashlight
sheets/pillow/blanket
two power strips
two forty foot extension cords
small 9 inch fan
cell phone
charger
laptop and accessories
digital camera and docking station
normal disney clothing + decent in public sleepwear
daypack with toiletries to carry to comfort station
small bottle of laundry detergent
several dryer sheets in ziploc bag
shower shoes
plastic sheeting for groundcloth
a plastic tablecloth for picnic table.
Towels/washcloths
Clothesline
Collapsible cooler
Package of Cable Ties for extension cord management
Laundry sack.
A case of sodas distributed in small areas throughout my luggage.
The camping gear fits in two Sterilite bins that I have attached a strap to to keep the lid on, but the airlines can open them easily. They are the maximum size the airlines will allow.
My clothing fits in a carry on size suitcase and then my computer bag also comes with me as a carry-on.
I kept the computer locked up at the desk at the reception outpost, and dropped by there a couple times during the week to download pictures and check email.
I don't cook when I tent camp at Ft. Wilderness, so things like a grill or charcoal or food is not necessary for me.
I also washed clothing every evening. Since the washers/dryers are right at the comfort station, it is easy. I would drop by and start the washer, then went to my shower, then after my shower, I would rotate the laundry to the dryer, then go back to my campsite (very close to the comfort station) and read a bit and call home, then go get the clothes out of the dryer. That way I brought very little clothing with me.
I hope this helps. I LOVE tent camping at Ft. Wilderness.
Unfortunately, I won't be doing that this December as they didn't discount the campground and I can get a Value resort for only a few dollars more each night.
