Why are Plane Tickets so Expensive Zipper Pouch

Why are plane tickets so expensive? Like, you're literally already going there. Cant you just give me a ride zipper pouch. Our everyday bags are large and luxurious! They're made of 100% durable cotton canvas, with a gold zipper and leather zipper pull. They have a gusseted bottom, and at 9" wide by 7" tall, they're significantly bigger than our zipper pouches, and have a high-end feel. They're the perfect size for makeup, nail polish, coupons, spending money, receipts, office supplies, and so much more! The perfect gift for the travelers in your life
