My first BA flight was on the 5th February 2015, from Heathrow to Budapest. My only flights prior to that had been with Easyjet and Ryanair - I remember being in awe at having a row of three seats to ourselves and the fact that I got a free sandwich and drink! Thanks to Tesco Clubcard it'd cost me 21,000 Avios + £150 which I thought was a bargain. It was a Heathrow Terminal 3 departure - I'd never have comprehended my travel progressing to the point of sipping champagne in the CX lounges there today!
