If I did a paid upgrade on one leg of the journey, can I still place a bid for a different leg?
I booked a super-cheap (K) TATL trip, and upgraded the first TATL leg to biz (P) paid. I would like to upgrade the return TATL portion to PE, but at the moment there is no N availability, I assume that was the reason why I was not offered a paid upgrade. Now I still see the upgrade button on the itinerary website, but it leads to an error website, and I do not see the MyOffer button anymore.
Did you confirm if this is the case? I did this same thing - paid for an upgrade leg and now the offer option for a different leg is gone. Pretty bummed about this as I'll need to count on cash upgrade space at this point or paying for PE instead of my planned biz upgrade.
Update: Spoke with LH - Once you do any paid upgrades, MyOffer is no longer available. If you refund the upgrade, there's no guarantee MyOffer would re-appear, either. Ugh.
