Somewhat shocked by the service on the silver line today. I booked LHR-NRT via HEL return today on the BA website. First and last sectors are BA flight numbers operated by Finnair and longhauls are JAL numbered and operated. Seat selection was not available online either in MMB or on Finnair website so I called the silver line. The agent did reserve seats on Finnair but then told me they had been deleted and I would need to contact Finnair and then JAL. When I asked him how to contact Finnair his suggestion was that I should google their number!

Surely if his system didn't show the number to call at another One World airline, basic customer service would suggest that he could find it out for the customer (maybe by googling it...).

Is this a helpline or a wind-up line?
