Does BA Silver still have additional checked baggage allowance in Euro Traveller economy on a baggage-eligible fare?
The BA website only references World Traveller as having the additional allowance:

Silver / Oneworld Sapphire

Two checked bags when travelling in economy (World Traveller)
For everyone on your booking*, except on hand baggage only (Basic) fares, where there is no checked baggage allowance.

It does mention Euro(or Domestic) travel

Thanks

A weight allowance of 32kg (70lb) per checked bag
