Flying 7 week old rescued puppies....not ideal, but? - crossposting

I have a litter of 5 pups I have rescued and raised. They are nearly 7 weeks old, but given circumstances, I now have limited options of what to do now as there is no shelter near me, and I have to suddenly move to a different city this week and have no one to look after them for me:

1. Give them away to people I know will badly mistreat them - which I will not do.

2. Fly them with me on a 45min flight and get them to a large city where I have a lot more options to find a good home, or at worst a shelter that will rehome them.

3. Take them to a vet and euthanase them all - which I really don't want to do as they are beautiful puppies and I have put a lot of work into socialising them etc.

4. Try and organise to drive them (over 10hr drive) to the same city as I am flying to - but I have next to no time to organise this and can't rely on anyone else.

I am leaning towards flying them because even though they are a little young, a 45 min flight versus a 10+ hr car ride seems like it might be a less stressful option, and I know they will get to the destination. I am concerned about possible dehydration from the flight though - but it is 45 mins max in the air, not several hours so was wondering if it would not be so bad? They are strong healthy pups.

What do you think? In this circumstance do you think it is worth the risk? If I leave them here they will be badly mistreated and have a horrible life....if I euthanse them its all been for nothing and they dont even have a chance....Has anyone flown pups this young?

It sounds like flying is the way to go. Personally, I've never flown with a puppy or older dog, but I know that many people who are into showing and buy dogs from overseas ship puppies without side effects that I've noticed.

Hopefully someone with more experience can post. But in my opinion, euthanizing/setting the puppies up for mistreatment is much worse than a 45 minute flight, stressful or not.

This thread's old and the OP had 2. I'll post basically the same thing I did in the other though for reference sake.
1. 7 week old puppies aren't allowed to fly for one, they must be 8+ weeks old. That's airline and USDA rules.
2. A passenger may only fly with 1 animal for excess baggage per person going, so they'll all have to go cargo once they are 8+ weeks old, plus weather restrictions and health certificates.
