I have a client that wants to book and around the world ticket in business class I haven't booked an RTW ticket in more than 30 years. Are there any agents out there that understand how it works that would be willing to give me 10 minutes of their time to get me started in the right direction? Also, if I recall it is quite time consuming, I'm curious if agents out there charge a higher service fee for them. I'm thinking $200.00....would love thoughts on this as well. Thank you in advance.
