i think the folks at Citi are working hard to promote their product and leaving no stone unturned to bring this card to be one of the best travel benefits card around. I know some people at Citi and we discussed this a few times, that is where my view comes from. Also, at this point of time, there are quite some marketing budget being put behind this. They are out to teach 9W a lesson and when ego/competition is at play, it only helps the customer better.
Being one of the early adaptors of this card, I got the 1200 buck codes in Dec 2011, however, they raised the value to 1500 without even asking for it.
So, while I can't use these on BOM-DEL, I won't exactly blame Citi for it, because I can always use it on a smaller segment and save quite some money still.
The card is good, no doubt - that's why I took it. But it is annoying when you see that the route you could've used can't be used just because of INR 20!
Of course seeing that in light of the INR 1200 limit earlier, it is still better.
