At first we contacted for flights from London to Dubai in business class with Emirates, businessclassglobal offered us a decent offer but they had something better with With Etihad Air in first class at %45 off the online price we went for it. Businessclassglobal.com or https://bcgflights.com/ as they call themselves also arranged a comp driver on the round trip so it was great.
I used Business Class Global.com for our family trip from London to Melbourne,
And we got great pricing on First Class tickets,
Would definitely use them again.
