It’s either BA CE or the same crappy seats on LOT or Lufthansa, with a transfer. Alternatively, you can pay a fortune to go in business on TK or QR, but it’s definitely not worth the money or extra time. I lived in Tbilisi for 6 months, when BA had stopped their direct flights, and it was a miserable trip to get there and back. Horrible timings and uncomfortable seats. Just be thankful that you can go direct!
