Hi,
I was browsing on qatarairways.com for a tickets to MLE (from PRG) on a QR operated flights and I just checked for fun the Flight + Hotel section and I am quite astonished with the prices. Simply if I just search for the very same flights included in the flights+hotel bundle on qatar website I get a price around 7000USD for the flights itself, but whole package (flights + hotel) with the same flights cost around 9200USD. The funny thing is that the hotel listing price itself without flights is around 1000USD/night. So the question is how so? Is there some hidden problem or some missing surcharge?

The only suspicious thing I noticed is that you are paying to some TUI company based in Singapore so I guess the flights are purchased from 3rd party OTA? If that is the case can you upgraded your flight using AVIOS or is it forbidden if you did not purchase the flights directly with QR?
