Who to believe?
 

The Qatar QSuite page mentions a number of flight numbers that have the Q Suite however when I check SeatGuru, there is quite a bit of discrepancy.

Which should be taken as correct or if not, at least more accurate?

edit: I am talking about this page https://www.qatarairways.com/en/onboard/qsuite.html#

For example it says Boston, Montreal and Chicago are all serviced by QSuite configs but SeatGuru disagrees.

In any dispute about accuracy between Seat Guru and ANYBODY else..... I would back...ANYBODY ELSE. ;)

Noted. Thank you. I found a few other sources, specifically https://www.premium-flights.com/all-.../#qsuiteplanes lists all Q Suite aircraft. I guess it's a bit of a crap shoot but here we go :D

Remember rule 1 - never book a QR itinerary on the basis of the scheduled equipment!

Totally agree with that!
Even I did rebook 2 times (fee waived by QR), my flights got changed from Qsuite to non Qsuite 4 times ;-)

Here's another resource which was mentioned on here recently and claims to give a regularly updated analysis of Q Suite routes.

This makes me sad. Sorry to hear that.

Thank you.

Thank you :-)
It seems, that I am quite unlucky with that - my overall statistic says, that more than 2/3 of my booked Qsuite flights were changed to non Qsuite...at a base of roughly 4 to 6 legs per month.

Wow. Can I ask which is your home-base airport and is there a reason it seems to happen more frequently there?

Mainly I go between MUC and BKK. If there is a special reason for frequent change? At least I do not know a reason for - maybe it´s just my bad luck ;-)
