This April and May I had a couple of flights from VIE to IST and to ESB on TK tickets on TK as well as TK code sharing flights (operated by OS). My experiences there were not necessarily pleasant so I decided to ask TK for comment writing some mails to
[email protected] . No response so far
Let me share my
best story a journey from ESB to VIE via IST. All under TK ticket no. ESB to IST on TK metal. IST to VIE on OS metal.
The check-in in ESB @ the CIP Lounge was great, except that they could not check me through to VIE and asked me to get a 2nd BP in IST from the OS counter but they can check my luggage through

.
Arrived in IST I needed to
run from domestic to international terminal, go to the OS counter where a very polite and welcoming young gentlemen explained me that
he is very sorry, but he can only give me a middle seat - they did not know that I would arrive here - but if he would have known he would preallocate my preference as a SEN.

.
Being late already they would let me in the priority line for emigration telling me that is only for TK-Gold members

Having in mind that I had 1:30 between the flights, I was surprised that I could not use the lounge as my flight was already on last call.
All in all: I'll try to avoid TK tickets on *A metal.
I don't know if I expect to much if I want to check in all my *A flights (on the same ticket) of a trip at once. Any similar experiences, or was this just a dark cloud above my head?
