Hi All
two weeks ago I was offered a free upgrade from Comfort to biz when I was looking at seats, seems I was too slow to confirm,. Called DL and they said that is offered usually 24hrs in advance. Is there a discussion thread on this saying how it works? I looked but only see miles/ status etc. I have zero status so I can only assume it's once all status folks have been served if there is space left they offer upgrades from comfort to biz
This was BOS-LAX.
