Using Here-Strings to help search United Airlines for Flight Dates

As many of you know, I am fortunate to teach Windows PowerShell, Server, and Client all over the world.  One thing that I do not do very often is use my air miles.  This is has been a very deliberate action because I wanted to make sure that when my wife decides to fly to Europe with me, she will do so in style. 

Well, the time has come.  I’m heading over to Europe to speak at the PowerShell Conference in a few months and my wife and I are going to spend some time together hunting down what we hope will be distant relatives and doing a little sightseeing.  So, I’m burning the air miles to fly family to my home to house sit and for us to fly over the pond in United Polaris Class.  My wife does not like long flights so I am determine to spend the air miles wisely to make sure she is as comfortable as possible.  I’ve made the flight many times in coach, but I would be a bad husband if I did not splurge a bit on my wife. Below is the difference.


What I usually fly…. Economy.

Our schedule is extremely flexible so I’m searching all of the airports in central Europe for days when United puts a premium cabin “on sale”, so to speak, for award mile use.  To help make this daily ritual less time consuming, and to give me a good lesson to share on Here-Strings with my class, I came up with the code below.

A few things first.  If you have a United Mileage Plus account, open your default web browser and log in.  Leave the browser open when you execute the code. Otherwise the queries will not be executed with your account.

You will also need to manually search for award travel to each destination.  You will need to replace my URL strings with yours for each search that you make.

Finally, you will need to replace the date component of the URL with $FlightDate.  Look for a date with a format of YYYY-MM-DD in the URL from United.  It is easy to find.

Once done, just save the code and press F5 to put it in memory. (You will need to change the default values of the parameters to meet your desired travel date. I marked the 3 places in the param block of the code.)

Type Search-United and press Enter.  All of your queries will run at the same time.  Remember to start this process 6 months in advance if possible.  This will help you find more award mile saving dates.

Function Search-United
Param (
    $Month = <#Replace with your default Month#>,
    $Day = <#Replace with your default Day#>,
    $Year = <#Replace with your default Year#>

#Create a DateTime object based on the flight date.
[DateTime]$Date = "$Month-$Day-$Year"

# Convert that DateTime object into the format the United website requires.
$FlightDate = $Date.GetDateTimeFormats().split("`n")[5]

# Here-String to list all destinations to check.
$SearchList = @"$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1$FlightDate&tt=1&at=1&sc=7&px=2&taxng=1&idx=1

# Open a web page for each destination.
$SearchList.Split("`n") | ForEach-Object {Start-Process -FilePath $_}

Allows you to search multiple destinations at United Airlines.

Allows you to search multiple destinations at United Airlines.

First you must open your default web browser and log into your United Mileage
Plus account.  Mileage Plus members receive better access to award miles
savings so you should see more options.

You must manually search each destination and make sure to select
"Award Travel" on the website.

Copy the web address into the Here-String above. Replace the date in
the string with $FlightDate.  The string to replace will bi in the
format YYYY-MM-DD.

Run this code when you want to check for award travel.

The numeric value of the month to travel.

The numeric value of the day to travel.

The numeric value of the year to travel.


Opens the United website and looks for award travel on the default dates.

Search-United -Month 6 -Day 15 -Year 2017
