Add a bit of extra time at check in at Tambo. WHen I went thru in April, you had your normal check in person, then they have to get a supervisor involved. Took a good 15-20 minutes at check in counter, then off to SAP. We had used African Sky for permits, and Gilbert was there to get us thru it, Defenietly worth the $$, he grabbed us and we went to the head of the line.I had no issues with Qatar. I guess it is who you talk to. Houston was a breeze checking in luggage and firearms. 2 rifles in one Pelican case. I had submitted a few documents to the special services dept at Qatar. Will find out in a few more days how easy Tambo check in is when I leave
