I had an interesting experience in a journey from LHR to CPT via DBX. My flight was booked through QF (points), but the actual metal was BA LHR-DBX and EK DBX-CPT. When I arrived at the F check-in at LHR was informed that BA could only give me a boarding pass from LHR to DBX, as BA does not have a cooperation with EK. Additionally, they informed me that my luggage could only be tagged through to DBX. This was a slight problem, as I only had 1.25 hr layover in DBX.
Flight in BA (Premium econ) was interesting - one of the passengers was clearly more plastic than flesh, and had everybody looking at "her" walking down the aisle. But the interesting thing was what she was doing to a fellow passenger under their flight blanket (I'll let you guess) - this was being watched by many other passengers, more gob-smacked than angry!
So, we arrive in DBX. FA said to me that she wondered whether said-woman had been to DBX before, because it was likely that she would melt in the heat!
Then having to deal with DBX airport - I was sent from one floor to the next, then one terminal to the next, and then back again. EK would not give me a boarding pass as the gate had closed. I was in the terminal so took my chance of running to the gate and hope for the best. Strangely, the gate attendant let me through, without boarding pass! Well, I thought I'm going to get on this plane, but heaven knows what is going to happen to me luggage.
So, got on the flight, bound for CPT. Over Yemen somewhere, some guy a couple of rows back starts yelling at another guy and calling him racist. Then a big punch-up starts, with one of the guys' toupe flying all over the place. This went on for a while. And where were the EK FAs? Standing watching!! The two guys were eventually separated by passengers.
Arrive in CPT. Told that my bags (which they showed me pictures of) would arrive on the second daily flight to CPT. Four days later they eventually arrived!
All in all, a bizarre experience. I enjoyed CPT though, in my smelly clothes!
