I used travelnation service to build my roud-the-world flight ticket. My family and I (2 adults and 2 children) traveled for a year around the world from Jan 2022 to Jan 2023, i.e. during Covid. I am definitely happy with travelnation, especially with Liz who supported us. First of all, due to Covid, I had to wait for the very last minute before booking all tickets (2 weeks prior to departure). I tried to contact some other agencies focused on multi-destination long-lasting trips. Others told me it was just not possible with boarder closure. Only Tranvelnation made the effort to build a quote matching my itinerary (including Africa) Then I had to modify quite a few time my bookings while traveling. As said in the general terms, I had to pay taxes if changing an airport. But that said, Liz managed to get refunds for cancelled flights as well as found interesting flights so my overall budget was almost not impacted. During such a long trip, there were also unexpected flight changes. Whatever the day and whatever the time, I was able to get someone from Travelnation over the phone in a minute to get assistance. And at the end, we were never stucked anywhere and we felt travelnation's team really cared! Quite a long comment to say how happy I am about travelnation during our trip of a lifetime. Highly recommended.
