Matching plan validity to your trip
Too short and you rebuy; too long and you pay for days you never use.

How much buffer to add
A safe rule: add at least one day for short trips and two when you have connections or weather risk. A plan expiring on the way home leaves you offline exactly when it matters.

| Criterion | Short validity | Long validity |
|---|---|---|
| If your flight moves | Risks expiring before you fly home | Absorbs the change |
| Total price | Cheaper when the trip really is short | Higher, but usually cheaper per day |
| Rebuying | You may need a second plan | Not needed |
Pick Short validity
Fine when the dates are certain and genuinely short.
Pick Long validity
Better when the return date is uncertain or the routing has several connections.
