Airplane

I used to buy round-trip tickets from Tokyo to Fukuoka for under 18,000 yen during ANA's Super Value Sale, but now that the Super Value Sale is gone, can I no longer buy them for under 20,000 yen round-trip...? I wanted to fly back for under 20,000 yen on ANA or JAL, but it seems impossible 😭😭 I looked around and found SkyMark for 21,000 yen... It's late November, not even Christmas or New Year's 😭 Is it no longer possible to find cheap deals like I used to with the Super Value Sale...???? If you got a good deal during a sale, please tell me how much you paid for a round trip 😭 Also, if you have any recommended airlines or websites, please let me know 😭😭 Super Value Sale... (；ω；)
