Which Austrian seat category am I reserving, and is Legroom the same as Extra Legroom?

What this answer depends on

• Austrian published seat-category descriptions, particularly long-haul Legroom and Extra Legroom; not personal exit-row eligibility advice
• A forward location and extra knee room solve different needs. Austrian describes Preferred as a location category, while its long-haul Legroom and Extra Legroom descriptions distinguish the relationship to emergency-exit rows. Read the selected seat’s description in the booking instead of inferring the feature from the word “preferred.”
• Austrian’s conditions define the reservation by category rather than an absolute claim to the displayed number. Save the category and purchase confirmation so you can explain what was bought if the displayed seat later changes. A layout image is not a promise that the aircraft or exact number will remain unchanged.
• Austrian distinguishes long-haul Legroom outside emergency-exit rows from Extra Legroom generally at emergency-exit rows.
• Austrian Preferred seats concern a forward cabin location rather than an automatic extra-legroom entitlement.
• Austrian’s reservation conditions describe a seat category rather than an unconditional guarantee of the exact seat number.
