I flew back from Riga to LHR. I had special assistance on the LHR to Riga route which was five star. I then had special assistance through Riga Airport and the lady (Astra) assisted me to the gate even though security was empty and Riga airport was quiet, and drove me in a vehicle to passport control even though I am fine to walk. She was fantastic and reappeared to help me onto flight. I cannot praise BA enough for special assistance. Our flight had delays due to UK weather but the cabin crew were also caring and reassuring. I am so grateful to BA for customer service despite the terrible weather in LHR.
