Targeted Jet promotion for 40% bonus miles and 4 bonus tier points

Jet Airways is currently running what seems to be a targeted promotion to boost your tier points, with some bonus JP miles thrown into the mix. As someone whose travel has reduced quite substantially compared to the last few years, I find this reasonably useful as long as I'll be able to fly enough otherwise to renew my JP Gold status. 

Jet Privilege will give you 40% bonus miles and 4 bonus tier points for taking 4 Jet Airways flights between today (23 November 2015) and 22 December 2015. Simple as that. However, the offer is limited to taking 4 flights...meaning, flight more flights won't get you any more bonus miles or tier points. Here's an extract from the email I received.

Given that this seems like a targeted promotion, there isn't a registration required, nor is there a requirement to book tickets via one or more specified channels only. Here are some of the more important T&Cs:

• This promotion is applicable only for the JetPrivilege member to whom the email was addressed. Members who do not receive this email directly from JetPrivilege will not be eligible. 
• Eligible Activity is defined as Revenue Tickets booked during the Promotion Period on jetairways.com or any other channel, in Economy or Premiere or First Class, for one-way or return travel on any Jet Airways flights within India or International. Travel on Jet Airways marketed and operated flights and on Jet Airways International Codeshare flights operated by other Airlines will be counted towards an Eligible Activity. A Single journey on the same Jet Airways flight number will constitute 1 Eligible Activity. 
• The Promotion Period is limited to tickets booked between 23rd November 2015 – 22nd December 2015 (both days inclusive) for travel between 23rd November 2015 – 22nd December 2015 (both days inclusive). 
• Such members upon undertaking 4 Eligible Activities during the Promotion Period will earn a total of 40% Bonus JPMiles and 4 Bonus Tier Points 
• 40% Bonus JPMiles will be awarded on the Base JPMiles earned on each of the 4 Eligible Activities. 
• 1 Bonus Tier Points is awarded on each Eligible Activity thus a Total of 4 Bonus Tier Points awarded during the promotion. 
• Members who undertake less than 4 Eligible Activities will not Earn any Bonus JPMiles or Bonus Tier Points 
• Members will not earn any additional Bonus JPMiles or Bonus Tier Points under this promotion after completion of the 4 Eligible Activities even if they undertake more than 4 Eligible Activities during the Promotion period. 
• Bonus JPMiles and Bonus Tier Points earned under this campaign will be credited into the members account only upon completion of all 4 Eligible Activities. 
• Other Terms & Conditions Apply

As a reminder, Jet Privilege's Dynamic Tier Review requires tier miles / tier points as follows, to retain / renew status and to upgrade tiers:

The reason I said this promotion works for me well, is the bonus tier points. Because most of my flights on Jet are domestic (in fact, I can barely recall the last time I flew Jet on an international sector), the hard way (by actually flying) is the only way I can keep my status. And because of that, I rely more on tier points than actual miles flown, to get me there.
