If you remove the wheels you have to crush-proof the dropouts with some form of axle replacement. Plastic tubes, rolled up corrugated card or something can be used. You can also use this inside cardboard boxes to reinforce against crush damage at the corners of the box and inside the frame angles and between spokes.
With plastic bags, use plumbing pipe insulation foam split tubes to protect every part of the bike. The problem is to source the material for the return journey. If you can stash your materials at a local hotel that is best. You can buy or get the stuff at DIY stores. Heavy duty polythene sheet can be found as waste packing material and used with ducktape.
Beware that drinks bottles may need manual inspection.
Think about how and where you carry your packing tools and materials eg tape, knife. Make sure you check in the bike before you check in the packing kit.
Some airports require x ray of the packed bike and some machines are smaller than others. I had a bike that passed through Heathrow fully assembled inside a bag but on the return journey I had to remove the front wheel to squeeze through the scanner at a small local airport. Small airports are usually much better and less stressful for bike travel.
