I recently flew from Abu Dhabi to Zurich (one way ticket) and regularly fly with Etihad so I am a platinum guest member. I had originally booked an economy ticket and prior to my flight I paid in cash (no miles) for an upgraded business class ticket. I upgraded the full one way ticket that was purchased.
At check in I was surprised and disappointed to be confronted with additional fees for baggage. As I did not originally purchase a business ticket, rather I paid for an upgrade, I was told I was not eligible to the baggage allowance of a business class guest. Therefore I had to pay a thousand additional dirhams for additional luggage. Astounding. Etihad used to be an outstanding airline, from the courtesy shown by employees, to the service onboard and now it does not think about the comfort of their guest. When boarding the plane, via a bus and staircase, as well as being 30weeks pregnant and traveling alone, no Etihad member offered to help me. Instead another passenger very kindly helped stow my hand luggage on board.
After contacting Etihad Guest, via email and many social network channels, regarding paying the additional fee for baggage, I was again informed, as it was an upgraded tickets, you are not entitled to the business class luggage allowance which I find baffling. Heads up people, you no longer get the perks of a business class ticket if you upgrade.
