Air Seychelles don't have a bag drop desk at arrivals (just after customs), so you have to take yourselves up the escalators to check in.

Lounges have showers but don't expect more than snacks and light bites, some lounges might still be pre-packaged food (covid measure that hasn't gone away at some places since it is more hygienic). If you arrive on time, by the time you are through immigration you should be able to check in your luggage and then have a breakfast at the food hall (landside) before going through security.
