I've already asked in another thread for clarification, but no answer there, so I try it here, especially also because TK hasn't replied to me for more than 2 weeks now on this question. Maybe also the agents are not sure about that?

Anadolujet EcoJet tariff does not include check-in luggage. Are Elite/Elite+ members nevertheless allowed to check in 20 kg of free luggage on international (and also connected domestic segments) Anadolujet flights in EcoJet tariff even though this tariff normally does not include check-in luggage?

Please do not mix up this Anadolujet EcoJet tariff with Turkish Airlines (operated by TK) EcoFly tariff. In the latter case, I know (from reports here on the forum) that it is allowed. But I'm wondering if the same is also valid for Anadolujet EcoJet tariff, especially since I have received mixed information/experiences on that, e.g. in TBS I have been rejected to check-in 20 kg of luggage for free as an Elite on Anadolujet EcoJet tariff (however, I'm not sure if the staff there is very reliable when it comes to such questions...).

In general, it's pretty annoying that Anadolujet/Turkish Airlines do not give any substantial information on this on their website!
