let me think..... tsa or homeland security confiscated a christmas cake ...... elderly woman had to leave her cane..... I was at Vegas airport when they confiscated a beautiful titanium multitool from me... ( no blade or knife, mind you )
And you want to take a bike INSIDE the plane...
Now, there will be a bunch of folks, jumping on this thread that they have done this and done that in the past.... some even currently,
Some will tell stories how easy and painless...... you dont hear all too much noise from people who have paid penalties and late check in and maybe even lost their bikes..... ( you never hear about loosers coming back from Vegas either... they all won, had a good time, didnt loose nuttin....)
What I am saying is that you better be very carefull, there might even be some brand propaganda going on, lets say the answers are heavily biased in one direction.
here a crude size comparison, keep in mind that the mks pedals will be out and have only a very short stub sticking in the crank.
Having said that, you will be best off to get a small folder without all to much stuff hanging off it.... ( carriers, fenders, lights, etc etc etc) with quick release wheels.... than u get a regular old used Samsonite suitcase, spend 5 minutes to take things apart and 10 minutes to put stuff back together ... and just check it in as regular stuff....
there is a weight limit for overhead bins as well, not just size. There is No difference in allowable size for a big plane versus a standard one, plus those planes regulary get switched around, and all of the sudden you are sitting in a smaller plan ... than what ?
