Could fuel limitations therefore [have] been a factor . . . it may be assumed that there was sufficient traffic about to expect some delay in the event of a missed approach.
1. I'm only SLF, but that scenario seems unlikely. (Note: I'm assuming you are referring to running short on fuel, and not simply the added cost of each additional gallon that would have to be loaded once they landed).
If fuel was running short - then in the event of a GA, wouldn't they simply declare a fuel emergency and obtain priority for making second attempt? Presumably also had reserves to reach alternate airport, if necessary. Unlikely they were playing Medellin roulette.
Fire afterwards also suggests had fuel. And FDR/CVR should have revealed if it was an issue (and highly likely that would already have been mentioned in the information released and actions taken).
2. Time lost - in so far as running behind schedule if had to GA and wait in line, might be more likely a consideration (if it even was).
But from what has been posted thus far, it doesn't appear they had any idea (until final moments) that weren't on track for a routine landing.
That they should have realized it sooner -- and why they didn't -- is another matter. As others already have discussed in detail.
