A deposit is a small fee (percentage of the flight) that you pay to secure your flight when booking.
Usually, you don't have to pay back the remainder of the flight until the final few weeks leading up to the flight. However, you do need to pay the balance of your flight before you jet off.
In some cases, if you need to cancel your flight, you won't have to pay the remaining balance of your flight. But, you'll lose your deposit.
In most cases, the remaining balance will have to be paid in full and in one go.
Most airlines don't allow you to book flights with a deposit. However, when you book through Alternative Airlines you can secure your flights with over 650+ airlines for a small upfront deposit from 10% (or 20% if you're in the US). We are putting the freedom back into flying with deposits that allow you to plan in advance whilst securing today's prices without the hassle of steep upfront costs.
By putting a deposit on your flights, you can slowly pay off the ticket total without a large amount of money leaving your account at one time.
