I'm not sure why you're being rude. You have shown up here and have asked for help with no details for what you want. Plenty of people, myself included, have been happy to help others with our experiences + booking processes.

So far, all we know after your second post is that you need to be in India next month and that you're willing to either leave from the UK or the EU. This thread and others like it have quite a few details on the most cost-effective departure destinations. Reading them would inform your initial thoughts on where to leave from (likely OSL), how you would pay (there's no option to pay for an RTW with Avios), and whether or not this option makes sense for you (you can't end your trip in India, so you'll need to either travel to India and then make your way back separately to the UK before heading back to India for the remainder of your trip OR go around the world between now and next month, end up in India, and then use your flight home from India to get back to the UK before dropping the final leg to OSL). All of that would be quite clear if you had actually read this thread or the others in the Oneworld section as opposed to being dismissive and antagonistic.
