Remarks: One of only handful of non-ER 300s that have been built. Along with Emirates, there are three other airlines who operate these non-ER versions. Do you know who are the other three? ;o)
Update: Thanks to Calvin O for pointing out the fact that JAL, ANA and KAL also operates these in addition to UAE, SIA, THA and CPA. I missed to notice the fore mentioned three. So not 4 but a total of 7 operators for the non-ER 300s.
