I worked in Zim and started an airline there, and I can easily see the potential for a UK Zim connection. Every time I got off the EK flight I was stunned by how many Brits there were in the queue at HRE immigration.
A330 not a bad choice given that 321XLR are like hen’s teeth. Just hope they have better advisors than some other start ups! (Happy to give them some pro bono help. I love Zim and its people!)
I wish them good luck!
