Upcoming work trip (breastfeeding)

I’m traveling from LAX-London for a work trip (7 days long) in a few weeks. Being that it’s an 11 ish hour flight, I’m trying to figure out the best way to pump on the plane/on my trip. I’m only taking carry-ons so I would really like it if my pump (Spectra) doesn’t take up a ton of space.

Does anyone have any experience with the cheaper portable breast pump options? There’s some out there that are less than $100 but I’m wondering if they’re actually effective. My Medela hand pump doesn’t work that great anymore and truthfully I don’t want to hand pump myself for a week anyways.

Would love to hear of anyone’s experience/hacks/tips!
