So why do you fly with them this time
I decided to take advantage of the biz sale which we normally would not be able to use, as we would do a return to BOM, rather than back to the US, plus the 2 flight segments versus the 3 segments on LH (they also had a similar fare as well, which I could have bought)
IMHO to allow you for changing to any flight on the same day is a generous offer.
Oh wow - for a business ticket? Interesting.
