Currently have JMK-ATH-FCO on a saver award ticket with 23kg.
Was thinking of bidding for an upgrade for JMK-ATH leg for extra piece of baggage for the whole trip.
Is this possible?
Yes, did this in 2021 but in reverse.
RHO-ATH-FCO but used Gold upgrade on ATH-FCO segment.
Was granted 32x3kg for baggage allowance.
Check-in agent might need a casual reminder of the greater allowance if First segment is Y, Second segment is J.
