POST/v2/cart/validate-fare

Revalidate the fare

Ask the provider if the fare moved, immediately before booking.

Bearer tokenAuthority: B2C_CART_VALIDATEhttps://booking.aerolink.dev

priceChanged is derived from the upstream message FARE_CHANGE_UPSTREAM, not from comparing the two numbers. Both price and oldPrice carry the same markup, so a marked-up cart does not appear to have jumped when the fare has not moved.
