Immersion during the
day, even on the day following the appropriate night for immersion, is only permitted in a very narrow range of circumstances. Please write back if there is any additional relevant detail (e.g., problems conceiving). A conflicting flight is not, in and of itself, basis to immerse during the day. In this case, you should make arrangements to immerse on Thursday night.
Depending on the timing and length of your flight, it might be possible to arrange for immersion en route to the airport or immediately upon arrival (if you arrive early enough that night). Do explore these possibilities, and let us know if we can help planning the logistics.
Thank you for your kind words. Please pass on our link to your friends!
