In high season the United, Delta Atlanta, American Charlotte and Air Canada flights all cluster on Saturdays.

Several of the winter-only US and Canadian flights run once a week, on Saturdays. On those afternoons the single check-in hall and security line are at their busiest, so arrive early. American's daily Miami flight (twice daily 17 Dec 2026–5 Apr 2027) and JetBlue's JFK days avoid that peak. St Kitts stays on UTC−4 all year.

Every airline uses the same building, but entry starts online: an approved eTA is mandatory before you fly.

Apply on the St Kitts and Nevis e-Border app or knatravelform.kn (US$17, valid 90 days). App users can use the facial-biometric fast-track corridor on arrival. You walk across the apron with no jet bridges, then go through immigration, baggage claim and customs to the taxi stand outside arrivals.

A restaurant/bar, duty-free and a gift shop are airside, but no official outlet list or hours exist.

Traveller guides agree on a small airside restaurant/bar plus duty-free, but SCASPA does not publish names or opening times. Downtown Basseterre and Frigate Bay are about 10–15 minutes away by taxi at US$10–20 regulated fares, so a proper meal in town before an afternoon departure is easy.

No airline, Priority Pass or card lounge exists at SKB; the only option is KayanJet's paid private terminal.

American lists SKB clubs and lounges as not available. KayanJet costs US$235 per adult plus 10% tax (US$150 for local passport holders and residents). It covers arrivals on any flight but departures only to non-US destinations. oneworld (AA, BA), SkyTeam (Delta) and Star (United, Air Canada) status still gives priority check-in at the airline counters.
