RUN RUN RUN - this company is a scam! They might deliver biz class tickets if everything goes right but once something is cancelled or delayed, YOU will never hear from them again. I first booked with Top Business Class in 2019 for a trip in 2020. Covid hit and our cruise was cancelled. Max was our agent and at first he was really helpful. He said we have a voucher to use in the next 2 years. In 2021, Max suddenly never returned my phone calls and emails. In the end, we couldn't wait any longer and bought other tickets for our international flight. When I finally got a hold of Max again, he said he didn't know what happened but he could give a 1 year extension on the 2 limit. Now in 2022, I'm told Max has left the company, so I talked to Andrey the Manager. He said David would handle my request. Now I'm getting the same NON-RESPONSE from David. No returned phone calls or emails.
So if you don't mind losing a couple thousand dollars, go with this company, otherwise you should RUN!
