Web alarm clock for 6:06 a.m.
You are finishing your last check and heading out at 6:06 am, leaving enough room to pass security before the first flight between the islands. An alarm now can mark the point when preparations stop and the trip begins, without letting small chores stretch toward 7:00 am. Keep your ID and boarding details where you can reach them quickly on arrival.
Your early departure depends on hearing the signal when expected, so test it beforehand at a comfortable volume rather than discovering a problem as you leave. Set a temporary alarm, confirm that the sound plays clearly, then remove the test and keep the 6:06 am setting. If you close the browser or let the phone sleep, the alarm may not sound, which could leave too little time for security before that first flight.
Before setting off for an inter-island flight this early, choose something simple to eat and take a small bottle of water if airport rules allow it. A familiar pandesal or banana is easier to manage while checking documents than a full breakfast. Save a heavier meal and extra coffee for after security, especially if queues make the 54 minutes before 7:00 am feel tighter than expected.
