Please stop looking for racism in each and every aspect of public discourse, it does way more harm than it has the potential to do good. The harm lies in the ever larger focus on things which have the potential to divide people, be they race or sex or gender or religion or any other section. In this case there may have been a suggestion of the pilots having undergone less rigorous training and the aircraft being maintained at a lower standard than would be the case for 1st world airlines. These things may be true or they may not be, the airline safety records are among the potential ways to ascertain the veracity of such statements. This has nothing whatsoever to do with race so it does not make sense to try to draw this in as a factor unless someone made explicit claims in that direction. I have not seen any such claims, if you can point at them - and I do mean explicit claims, not so-called 'dog whistles' as those are subjective - please do so, otherwise keep race out of this discussion.
