CupcakeFlew with Alaska Airlines-Apr 2026

Please bring a water bottle for hydration during the flight.

StephenFlew with United Airlines-Jan 2026

If you're trying to make a connecting flight make sure you allow PLENTY of time between flights or be prepared to miss the next flight. Make sure to use the restroom at the last possible moment before landing because you could be sitting on the taxiway for 5 more minutes... 5 more minutes... 5 more minutes... until it's been nearly 2 hours. Don't trust the airline provided ETA provided by apps they don't update it until long after you're delayed. If someone is showing up to give you a ride, make sure they have hours to wait for you.

RodFlew with United Airlines-Sep 2024

Yes! Don’t reserve a flight with less than 1 1/2 hour connection time or you have a good possibility of missing your connection.

Check the weather, or bring a. Raincoat! Being from sunny California, I forget it isn’t always sunshine in other states!
