Any lounge access changes would have to go hand in hand with you being able to select booking class on a BA holidays booking. My TPs mainly come from
one or two BA LH trips in J/F per year, then top up as needed with CE. The rest of my flying on BA is on low-cost holidays bookings, usually, as whenever we go away bike racing we need a car. Losing status benefits on those tickets would totally defeat the purpose of status chasing for me and therefore kill any loyalty to BA on LH.
