How much does a 21-day trip from London to Portugal cost?
Answer
A 21-day trip — 20 nights on the ground — for 2 travellers in 1 room is estimated at 5,400–8,600 GBP in total (flexible dates), around 3,500 GBP per person. Return flights are 200–550 GBP of that, about 5% of the mid figure, and spending in the destination is 5,100–8,100 GBP. The nearest supported length, 14 days, models 3,600–5,900 GBP (-32.1%).

Assumptions behind this figure
- 21 days, 2 travellers, flexible dates, departing from the London metro, priced in GBP.
- Travel style comes from the selector; the model prices that style, not a specific hotel or fare.

How certain this is
The range is the model's own low-to-high spread for this style and month. Real fares move with booking date and demand, so treat the mid figure as a planning anchor rather than a quote. Figures use broad planning rounding; the calculator may show finer rounding for the same inputs.
Who this suits / Who should think twice
Who this suits
- Travellers who can go in April, May, June, September and October, when the record rates conditions strongest.
- Trips built around food, beach and cities.
- Trip lengths between 8 and 14 days, the usual window in this destination's record.
Who should think twice
- Travellers who need a fixed, guaranteed price today should book directly rather than plan from an estimate.
Principal tradeoffs
- Shorter trips cut accommodation and ground spend but keep the full airfare, so the per-day cost rises.
- 21 days is longer than the record's usual 8–14-day window. Additional days add ground spending while this model holds the airfare fixed; the component figures above show each share.
- Rooms are priced at one per two travellers, rounded up, so a larger party raises the total and only lowers the per-person figure when the extra travellers fill a room that is already paid for. This is a reading of the recorded length bounds, not a break-even calculation and not an itinerary.
