AnneFlew with Alaska Airlines-Oct 2026
Can upgrade from Basic(no change, no refund) to changeable ticket for $100 more -BUT then you must pay another $75 to reserve that new seat PLUS any difference in airfare. Not as great for changing flights as for cancel & rebook using credit received for original booking.
LaveniaFlew with Alaska Airlines-Dec 2025
Pre-order your food. Make sure to bring your OWN device and be prepared to pay for WiFi to access entertainment for this long flight.
LaveniaFlew with Delta-Dec 2024
When heading to the West coast, we prefer “red eye” flights to help overcome the time change.
TonyFlew with Alaska Airlines-Dec 2024
Pack snacks or a good sandwich. Download your movies before you fly to avoid another FINE/FEE for internet charges. Pack light to avoid luggage fines/fees for check in baggage Don't pick a seat to avoid fines/fees

Be at the airport atleast 4 hours before the flight. TSA PRE CHECKS SUCKS AT ATLANTA AIRPORT
