One call. Delta and United, compared side by side.
Booking sites show you one carrier at a time. A live agent compares Delta and United side by side — fares, routings, layovers, and what it actually costs to change the ticket later.
Agents available 24 hours a day, 7 days a week.

Coverage
Carriers the agency can book
Domestic, transcontinental, and connecting itineraries on Delta Air Lines and United Airlines.
Airline names appear here for identification only, to describe which carriers can be booked. Flight Agent Line is not affiliated with, endorsed by, or acting on behalf of either of them, and all names and marks remain the property of their owners. To contact an airline directly, use the phone number published on that airline's own website.
What happens on the call
Three steps, usually under ten minutes
You are connected
Your call goes straight to an agent at the partner agency — not to us. Tell them the cities, dates, travelers, and how flexible you are. No account or card needed for a quote.
They compare Delta and United
The agent reads back two or three real fares with the airline, routing, layovers, and total price including taxes and any service fee.
Book it, or don't
If a fare works, the agency takes payment and emails the confirmation with the airline's own booking reference. Your contract is with them. If not, the call ends and you owe nothing.
Common reasons to call
The trips that are faster to book by phone
Search engines handle simple round trips well. Everything below tends to break booking sites — and is usually sorted out in one call.
Same-day flight change
Missed a connection or need an earlier flight today? An agent can check same-day change availability and standby options on Delta or United while you stay on the line.
Last-minute one-way fares
Booking inside 48 hours, funeral and family emergency travel, or a one-way home. Next available flights compared between Delta and United, not one airline's inventory alone.
Multi-city and open-jaw trips
Fly into one city, out of another, with stops in between. Priced by an agent, these are often cheaper than stitching separate tickets together.
Group booking, 10 or more
Weddings, teams, and company travel. Group fares come from the airline's group desk and are not shown online, so this one always needs a phone call.
Travel with an infant, pet, or wheelchair
Lap infants, in-cabin pet space, oxygen, and wheelchair assistance all have per-flight limits. The agent confirms them with the airline before you pay.
Name correction on a booked ticket
A misspelled last name or a passport that doesn't match the reservation. Rules differ by carrier and there is usually a deadline — call sooner rather than later.
Plain answers
Things other travel sites bury
Who am I actually calling?
[PARTNER AGENCY LEGAL NAME], an independent travel agency. Not an airline, and not us — we only connect the call. For an existing ticket booked elsewhere, the airline is usually the faster route.
How do you make money?
The agency pays us a fee for each qualified call we send. That fee comes out of their margin — it is not added to your fare. Any service fee on your booking is theirs, and they state it before taking payment.
What about my card details?
Given once, to the agency, at the point of booking. Never to us. A legitimate agent will not ask for a card to "hold" a fare, and will never ask for gift cards, wire transfers, or crypto. If that happens, hang up and tell us.
