You're being downvoted for a sarcatic remark but all these comments that simply point out obvious benefits seem less like genuine offers of advice and more like a way to keep damaging any big tech company.
I wasn't even being sarcastic: for me saving potentially hundreds of € is worth it, for some people they might like the "personal touch" of a travel agent.
"Travel agents offer a more personal touch"
No shit, who didn't know this?
