at one point of time airtel did clarify that you can queue a plan provided you have less than x number of days left in existing plan. not sure if it still applies today. there is a thread somewhere on the forum with details.

Hi! Please be informed that if you recharge with any unlimited pack (more than 180 days) before existing pack expiry your new pack will start. Kindly note the overall validity (Present plan validity and new plan's validity) should not exceed more than 180 days. Hope this helps! If there is something else you wish to discuss, DM me any time. Thank you, Lokesh
