I was about to edit in a disclaimer about not asking me that because I’ve never used it with Arch and was half joking because it’s probably a huge pain compared to the iso. I’m sure it works well for what it does for those who use it. But I’ve never done it specifically with Arch and you’d need to use Ethernet.
It’s not a huge pain when you have a motherboard with proper UEFI support and some basic EFI shell knowledge. You just need your thumb drive with an FAT32 filesystem, put the netboot EFI binary on it, boot into the shell and execute the binary. You will need a LAN cable for this because WiFi is not supported in UEFI (AFAIK). The netboot binary will download the ISO image into memory and start it right away.
An even better solution is to create the path “/EFI/BOOT/” on the thumb drive and rename the netboot binary to “BOOTx64.EFI”, put it into the folder and your BIOS will boot it automatically at startup. If not, you can select it as a valid boot partition in the BIOS menu.
How do I do that?
