A Family-Run El Cajon School That Books Discovery Flights Online
A family-owned school at Gillespie Field turned its website's Book Discovery Flight button into a live booking page and moved the office off spreadsheets.

Gillespie Flight Center is a family-owned flight school at Gillespie Field (KSEE) in El Cajon, California. It trains private, instrument, commercial, and instructor students on four older airframes with current avionics, and it runs scheduling, billing, and student records on Sky Schedule. Most new students start with a discovery flight that anyone can book online, straight from the school's website, at whatever hour they decide they want to fly.
A school that started with a first flight at Gillespie
The founder grew up in El Cajon and took his first flight at Gillespie Field when he was eight. Aviation runs in the family. His father, father-in-law, and mother-in-law were all pilots, and he inherited an airplane from his father-in-law before buying his own. His son has since joined the school as President.
The school is plain about what it is and what it is not. It is family-owned and family-run, built by San Diegans for San Diegans, and it is not a franchise or a corporate chain. It describes itself as not a pilot mill. Lesson plans are custom, scheduling is flexible, mentorship is one-on-one, and there are no membership fees. Between lessons there are seminars, ATC and DPE panels, and pilot meetups.
The fleet is small and carefully equipped. Two 1960s Cessna 172s fly with dual G5s, a GTN 650Xi, and ADS-B. A 1975 Beechcraft Sundowner carries a GNC 355, a GNS 430W, and dual AV-30s. A 1973 Cessna 150 rounds it out. For students who want structure on the ground too, the school runs a 10-week Private Pilot ground school in its classroom, two evenings a week, with the airplanes parked right outside.
The spreadsheet era
Before Sky Schedule, Gillespie Flight Center ran on spreadsheets and manual handoffs. The schedule lived in one place and student balances lived somewhere else. Cards on file were inconsistent, and billing meant rework at the end of the week. Leads from the website were one more thing to track by hand.
For a family team that wants its time going to students, that was the wrong place for the hours to go. The school also needed to switch without canceling flights or losing its history.
How the school runs now
The discovery flight books itself
The Book Discovery Flight button on Gillespie Flight Center's website opens the school's Sky Schedule booking page. A prospective student picks a time from live availability and books the two-hour visit: an hour touring the classroom and office, then an hour in the left seat with an instructor over San Diego.
That booking is also the start of the student's record. The lead lands in the same CRM as everyone else, and when the visitor decides to train, staff convert the lead to a student in one click instead of retyping a name and phone number.
One system for the office
Students, aircraft, the active schedule, and open balances came over to Sky Schedule together. Each student's saved card sits on their profile, ready for the next invoice. Invoices come from completed flights instead of a second pass at the desk, and reservation types match how the school actually flies, including training and rental. See how that works on our billing page.
What's different
The office has one place to look. A scheduled flight, the student who booked it, and the invoice that follows it all sit in the same record. The schedule is not rebuilt in a spreadsheet every Monday.
And the first impression has changed. Someone who has wanted to fly since they were a kid, the way the founder did, can go from the school's homepage to a confirmed discovery flight without waiting for a call back. For a school that promises a tight-knit community from day one, that first step is now the easy part.
