I fly a AA 757 into UIO more than a few times a year. Our 767's cannot fly into UIO, but are certified high enough for Bogota. I believe the 777 has a similar limit as the 767.
KLM (or Martinair?) had a morning MD11 arrival as we departed many times. More than a few DC-10 and DC-8 freighters have been present as well. Most of the outbound cargo is flowers so one might expect there should be plenty of power for those crews.
If IB did knock out the 35 ILS, it may only affect the non-RNAV approved operators. I believe the RW35 RNAV approach minimums are about <100 lower than the ILS.
