Salaam alaykum, you can pray your dhuhr salah before maghrib once you arrive in LA. You need to pray maghrib-'isha, and fajr on the flight back to London. If you can pray dhuhr-'asr before maghrib in London, then you can do that, as maghrib is now approx 6:00 pm.

They may pray together in one room. The husband has to pray in a position that is ahead of that of the wife.

Salamun Alaykum

You may pray Zuhr and Asr on the plane, or after you land in LA before Qaza.

In the return case you must pray at least those Salats that would become Qaza if you wait until landing.

Salam Alaykum,

Yes, in MOST cases, savings are khums applicable - even if one is saving money with the intention to perform the hajj, that savings must still have the Khums taken out on it.

Salaam Alaykum,

You will need to do your own calculations to determine where you will be in your flight at the average time for prayers and to determine if you need to pray or not. There are Apps for iOS and Android and also a web portal at https://www.halaltrip.com/prayertimes/inflight/ which may assist you in these regards.

Salam Alaykum,

Marriage, as it relates to two people, is something which both sides are comfortable with and is done on their own volition - there is no compelling one person to marry someone else - either by way of family and friends or by Allah. Yes, there are supplications which can be found in books such as "Selecting A Spouse: The Heavenly Path" by Abbas and Shaheen Merali which offers some prayers and supplications to assist in these regards.
