// History
//
// 10/2012 v1.2	Ryan Izzo  (ryanizzo.com)
//   Updated to use new Southwest Check In page, added validation
//
// 7/2014 v1.3 Ryan Izzo  (ryanizzo.com)
//   Moved script to GitHub since UserScripts appears dead
//
// 10/2014 v1.4 JR Hehnly (@stormchasing)
//   Added phone number entry to auto-text boarding pass docs to mobile device
//
// 3/28/2016 v1.5.1 Trevor McClellan (github.com/trevormcclellan)
//   Fixed phone number entry system
//
// 9/2017 v1.6 JR Hehnly (@stormchasing)
//   Initial changes to handle new Southwest confirmation lookup page
//
// 10/03/2017 v1.6.1 JR Hehnly (@stormchasing)
//   Got the script to a state where check-in works, but no auto-text boarding pass yet.
//   Have not determined what event listeners need to be triggered in the phone number form field.
//   Submits sucessfully if last phone number character is manually typed, but fails validation if it's only filled by the script.
//
// 3/02/2018 v1.7 JR Hehnly (@stormchasing)
//   Messy update to get this working somewhat reliably again.
//   Removed the 'text boarding pass' feature that wasn't working
//   Increased default start second from 02 to 04 since Southwest would complain about 'outside the 24 hour check-in window' when using 02
//
// 8/23/2019 v1.8 JR Hehnly (@stormchasing)
//   Adjusted default seconds to :07
//     Verified working with this setting
//   General code cleanup
//
// TODO: Use Southwest's server's time instead of the client's clock.
// TODO: Test select passenger page.

const DEFAULT_SECONDS = '07';

Anyone else still using this successfully? I just tried today, and did not receive a Boarding Pass confirmation message as listed here: https://www.theartoftravelhacking.com/automatic-check-southwest-flights/ , so after a few minutes I went ahead and checked in via the Southwest mobile app, and still received A38 boarding. Not bad, and it could be that this is a low volume flight, or, the script worked and did not give me a confirmation (?).

Worked again for me, using the default :04 delay with zero error messages. A50, which is good considering heavy travel around Thanksgiving, even in 2020. I'm still on v1.7--kind of apprehensive about updating since it's working flawlessly for me. I still have to go in to the app or the site and get my boarding pass, but that's no big deal to me. This time I used a standard Chrome window for my :04 delay, and had 4 incognito windows open with +2 sec delays for each. Didn't need them, unlike in the past.

Tried to use it to check in today and the initial check in click got triggered on time.

Then on the next page I got this error:

submitNow: An error has occurred: Cannot read properties of null (reading 'click')

I'm a Python programmer so not sure how to debug why submitNow() is triggering on the second page (which should be handled by autoPassengerPage()?).

No errors in the console either.

Today checked in for a US flight
Got the "Submit now. An error has occurred. Cannot read properties of null (reading 'click')
