southwest-headers

IYKYK. 😄

Working on Ubuntu 20.04 hosted by DigitalOcean. YMMV.

⚠️ February 2023 Update ⚠️

It appears the latest versions of Chrome (110) and undetected-chromedriver (3.4.6) produce invalid header files. Read this thread for a workaround.

Prerequisites

• python3
• pip3

Installation

Install Google Chrome

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb

Note: Tested and working with v108. v96 doesn't work, so please update Chrome if using a version older than v108.

Install Southwest Headers

git clone https://github.com/byalextran/southwest-headers
cd southwest-headers

pip3 install virtualenv
virtualenv env

env/bin/pip install -r requirements.txt

Updating Southwest Headers

cd southwest-headers
git pull
rm -rf env
virtualenv env
env/bin/pip install -r requirements.txt

Usage

No arguments saves the headers to southwest_headers.json in the current directory.

env/bin/python southwest-headers.py

Include an argument if you want to specify where the headers are saved to.

env/bin/python southwest-headers.py /PATH/TO/FILENAME.json

The JSON file can then be used in whatever app to auto check-in (assuming the script adds support for reading this file).

I've added support in my script here:

https://github.com/byalextran/southwest-checkin

Add a Cron Job

For now, I'd recommend running this script as a daily cronjob to ensure headers are refreshed regularly. They change periodically, so if this isn't done there's a chance you'll have expired headers when you try to check in.

crontab -e

And then copy/paste the following at the end of the file (making sure to update it with the absolute path):

0 2 * * *       cd /ABSOLUTE/PATH/TO/southwest-headers/ && env/bin/python southwest-headers.py

That would run at 2:00am every day with the file southwest_headers.json (the default filename) saved in the southwest-headers folder.
