Astraeus are sending their 3rd aircraft down today (another B757 in addition to the B757 / B737 already there). I spoke with the USAF slot controllers this morning and was advised that Port Au Prince (PAP / MTPP) arrivals are pretty much booked up with no slots available for heavy aircraft until round about 12th Feb (or call daily to check for cancellations). They can only accept 6 heavy aircraft per day (i guess B757 size upwards) due parking restrictions and each aircraft is subject to a maximum allowable ground time..... busy busy
