Airlines have now introduced a new class for their worst seats which cannot be named as Economy.

‘Last class’ seats have been introduced by airlines to compete with their budget counterparts such as Ryanair and EasyJet and include seats at the back of the plane, where it is noisier, or by a toilet with no refunds or upgrades.

The term is not officially introduced, but it is used by the employees of aviation industry to refer to seats that are a grade below those in economy class.

British Airways and Delta Airlines already offer tickets of that class.
