How Airlines Used to Handle Disruptions (and Why Travel Is More Complicated Today)

In the Jet Age, getting rebooked on a different carrier during delays was as simple as an agent writing 'Rule 240' on your ticket. What killed this traveler-friendly era?

When Switching Airlines Was a Breeze

A friend who worked for United in the 1990s recently shared fascinating insights about how airlines used to handle passengers when flights were delayed or cancelled. His observations reveal an airline industry that has changed dramatically over the past 30 years - and it's a world away from what travelers experience today...

The Paper Ticket Era

Back in the 1990s, airline tickets were actual paper documents with multiple coupons. A roundtrip ticket from Rochester to Des Moines on United would have four separate coupons - one for each flight segment (ROC-ORD, ORD-DSM, DSM-ORD, ORD-ROC).

Here's where it gets interesting: when your United flight was cancelled, the agent could simply write "Rule 240" on specific coupons and transfer you to American or USAir. Rule 240 was an industry standard that required airlines to accommodate passengers on other carriers during disruptions at no extra charge.

Behind the Scenes: The Airline Clearing House

You might wonder - if you paid United but flew on American, how did the money get sorted out? The answer was ingenious in its simplicity.

At the end of each day, airlines would send all their collected ticket coupons to their accounting departments. Then came the Airline Clearing House (ACH) - think of it as the industry's financial referee.

Rather than calculating the exact value of each individual coupon (imagine processing thousands daily!), the ACH used a formula based on coupon volume. If United collected 10,000 American coupons and American collected 10,000 United coupons, it was considered even. If the numbers were uneven, compensation was based on the difference - literally the thickness of the paper stacks.

Fast Forward to Today

Today's airline industry is exponentially more complex. Digital ticketing has replaced paper, but ironically, passenger flexibility has decreased dramatically. Most interline agreements have disappeared, meaning if your flight is cancelled, you're generally stuck waiting for your original airline to rebook you - hence those horror stories of passengers stranded for days.

What replaced simple interlining? Complex codeshare agreements and airline alliances. When you see multiple airline codes on your gate display (Delta, KLM, WestJet, Aeromexico), each carrier might receive a slice of your ticket revenue based on intricate alliance agreements.

The ACH still exists today with sophisticated computer systems handling these complex revenue splits, but the days of an agent simply writing "Rule 240" and putting you on the next available flight - regardless of carrier - are long gone.

It's amazing how an industry that's become more technologically advanced has, in some ways, become less passenger-friendly. What seemed like a simpler, more collaborative approach in the Jet Age (c.1958 into the 1990s) has evolved into today's fragmented, airline-specific booking system.
