1. Contact Alaska Airlines missed flight: Call their customer service number or visit their ticket counter as soon as possible to explain your situation. They may be able to book you on the next available flight or provide you with other options.

2. Check your travel insurance: If you purchased travel insurance, check the policy to see if it covers missed flights and what steps you need to take to make a claim.

3. Consider your options: Depending on your travel plans, you may need to make alternate arrangements, such as booking a new flight or changing your itinerary. You can also consider other modes of transportation, such as driving or taking a bus or train.

4. Learn from the experience: Reflect on what led to you missing the flight and see if there are any steps you can take in the future to prevent it from happening again, such as arriving at the airport earlier or double-checking your flight details.

Remember to stay calm and polite when speaking to airline staff, as they are more likely to help you if you treat them with respect.
