Looking to book business class from any US city to FRA and then from FRA to any city in India for 2nd week of Nov using UA miles (or even lifemiles). I know UA and LH rarely release business class seats on saver award these days. But I see some rare ones for tomorrow. Is it just some random luck or is there a pattern of LH and UA releasing minute seats on business? Should I have any hope of grabbing something when my dates gets closer (in 8-10 days)?
