Downstream General Service Error Southwest | How to Fix or Workaround it

If you’re seeing a “Downstream General Service Error” (or similar) when trying to use the Southwest Airlines website/app, here are some likely causes + what you can do.

✅ What it means

This type of error usually indicates that the front-end application you’re using (website or mobile app) attempted to call a back-end service (“downstream system”) which either:

• is temporarily unavailable or unstable;

• failed to respond in the allocated time;

• returned an unexpected response (error) that the front-end couldn’t handle.
  Users on forums report messages like “downstream general service error”, “downstream service unavailable”, “we are unable to complete your request” when booking or changing flights.
  Also, the Southwest site shows a general error message:

“We are currently unable to complete your request due to an undefined error. If this is the first time you have seen this message, please go back and try again.”

🛠 What you can try to fix or workaround it

Here are several steps you can take:

1. Refresh / Retry Later

   • The error may resolve once the downstream system recovers. Some users reported booking succeeded after waiting some time.

   • Best done with minimal changes so you avoid price changes if booking.

2. Switch device or browser

   • If you’re in the mobile app, try booking on the website (or vice-versa).

   • Try a different browser or clear your browser cache & cookies. Some guides indicate this may help for related errors like “500120227”.

   • Try switching network (e.g., from WiFi to mobile data) in case network/GEO issues are involved.

3. Avoid attempting many changes in short succession

   • If you repeatedly attempt booking/changing flights quickly, it may trigger failures or lockups. Forums suggest surging traffic (e.g., during disruptions) caused the error.

4. Check if the service is down broadly

   • Use services like Downdetector, or search forums for others experiencing the same issue. If many are affected then it’s likely a system-wide outage.

   • For example, one user noted “the same issue over here” and that the airline’s systems were affected.

5. Contact Southwest Customer Service

   • Since the error may involve internal systems of the airline, contacting them may allow you to complete your transaction or get better guidance.

   • For example: Phone: 1-800-I-FLY-SWA (1-800-435-9792).

   • Have your booking details ready (if relevant), what you attempted, and the exact error message / reference code (if shown).

⚠️ Important Considerations

• If you tried booking and your payment/payment method was charged but the booking didn’t show up, you need to track it carefully. Some users reported charges without a confirmation.

• Do not keep retrying aggressively without monitoring—multiple failed attempts might lock your “travel funds” or credits. One Reddit user noted advice: “do not try booking again till they take down the advisory, otherwise the funds will just get locked up again.”

• Keep screenshots or record the date/time/transaction ID of your attempt in case you need to dispute charges or claim leniency due to airline system issues.
