Delta flyers can now track their checked baggage via the Delta app. Simply enter your bag tag receipt number or scan the barcode (for iPhone users) and you can follow your bag’s journey from departure to arrival–including knowing which carousel to head for upon landing.

Delta customers can also now opt to purchase an annual Delta WiFi pass for $399.95 for unlimited, annual access to Gogo inflight Internet onboard all Delta WiFi-equipped flights. By early this year, more than 250 Delta Connection two-class jets will also offer WiFi.
