Remove last character from regex match

Question

I have strings that are concatenations of airline codes/flightnumbers, separated with ;. The airline code and flight number are either separated by a space or -. So some examples are:

AA-1234;UA 243;EK 23;
9W 23;B6-134

Now I want to grab the airline codes from this.

I came up with the following regex: [a-zA-Z0-9]{2}[ -]. This works to grab the airline codes but also includes the airlinecode-flightnumber separator. How would I adjust my regex to not include this?

`[a-zA-Z0-9]{2}(?=[ -])` or `([a-zA-Z0-9]{2})[ -]` – Wiktor Stribiżew Aug 13 '19 at 09:01 — Wiktor Stribiżew, Aug 13 '19 at 09:01
