Obvioulsly not, but a Ryanair ticket sometimes costs £10 and sometimes costs £500. Sometimes Interior sells out fast, sometimes Balcony, sometimes YC. Prices change so often and are totally flexible, not much sense to compare one exact date/ship/cabin/category/promo. I have seen a Fantastica Balcony cheaper than a Bella Inside.
If you like price for a special route and ship and cabin, a balcony for £763 for example 😉 , just grab it.
