Ok first of all this sentence is so wrong (grammer and senctence wise)
So what you want the answer to be is: He is traveling to the airport at about 11.
But what your question says: He is traveling the airport about 11.
Your just forgeting those little words that make a big differnce because your sentence makes no since whats so ever (not trying to be rude im just helping).
Well i hope you have a Merry Christmas and a Happy New Year :) i hope this is helpfull <3
