Pakistan, India and Sri Lanka account for much of the regional-plan choice here, reflecting a region that spans a huge mainland, islands and smaller states. Plans are therefore strongest for itineraries centred on those larger markets. A trip involving Bhutan, Maldives or another less-served member deserves country-by-country checking, because coverage can vary between regional offers. Routes built around the main markets are usually straightforward; those hinging on a quieter stop are less predictable.
