&gt; I fly Delta a lot and their economy comfort is not 300x the price. It&#x27;s a fraction of the ticket price.<p>I just checked, the cheapest I can find is 200x the ticket price (e.g. $500 Vs. $1000 for economy Vs. comfort+). 300x is definitely common too depending on how popular the flight is (e.g. $500 Vs. $1500).<p>&gt; Most Delta flights I&#x27;ve been on lately use a different recline system. The seat recline pivot seems to be near the arm rest and the seat bottom slides forward.<p>It depends how high the person behind knees are. If you&#x27;re cramped into the seat, your knees have to go higher to fit at all. The design you&#x27;re talking about only works when the seats aren&#x27;t too close together, once they get that close it still impedes leg&#x2F;knee room.<p>I&#x27;ve been on Delta flights a lot, they suck.
