// 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';
