Jewar Airport won't boost Sector 9 prices *that* much, right?

Been in my 2BHK in Sector 9 for 5 years now and thinking of upgrading to a 3BHK, maybe even a small villa. Noida Extension mein prices toh badh rahe hain, especially with all the infra projects. Sab Jewar Airport aur FNG Expressway ki baat karte hain, but I'm not sure if my current Sector 9 flat will see *that* much appreciation from it. Already have an EMI, so a new one needs to make sense. Is it just builder marketing ya genuinely kuch areas mein massive returns possible hain? Like, are properties near the Aqua Line extensions ya FNG corridor still affordable for an upgrade (say, ₹1.2-1.8 Cr range)? Or has the appreciation already peaked? I'm looking at Gaursons or Mahagun projects. What's the scene, community?
