I've got some advice having flown twice this year with clubs.
First of all, I got the same one Booyaka said,, the Mcgregor one. To be honest it's ok, but mine did suffer a puncturing tear to the backside material on it's first trip!

I got Mum to sew a patch in as a repair lol. Anyway the reason it happened is because I packed a stand bag and the top part of the legs protrude out a bit and this obviously rubbed against the bag. I've seen first hand what the baggage handlers do to the clubs. They ABSOLUTELY WILL BE CHUCKED AGGRESSIVELY and take loads of knocks. Remember, the handlers are picking up MULTIPLE buggies and car seats at each end, and treat all oversized baggage as the same. It will get battered.
So this is how I pack...
Buy some gaffer tape and have some cardboard and packaging material/bubble wrap/sponge or something handy.
- I take the heads off all woods and tape up the top and bottom to stop the screw falling out and getting lost. I then place them inside their covers and pack these inside the main golf bag surrounded by other soft things I am taking as well.
- I put socks on all the irons to stop them clattering against each other
- I place a crutch (as in from a pair of crutches we seem to have from old injuries!) inside the Golf bag and this is extended to be the longest item so any hits to the top hit the crutch first. There is a thing you can buy which does this exact job. You can search for "golf club shaft protector" or something like that. You could truly use anything you want as the brace.
- I then wrap a load of gaffer tape all around the clubs and pull them all in more centrally to sort of hold them in place a bit. Place some bubble wrap or sponge around them and gaffer that on.
- I then wrap and tape cardboard around the outside of the Golf bag especially focussing on any sticky out bits that would rub the golf bag bag, and also over where the Wood heads are in the bag.
- I then place the main golf bag in the Golf flight bag, and then place things like flip flops/sliders/towels/shoes etc all round the remaining room around the clubs sticking out the top to add more protection.
I also massively stack the Golf bag with loads of other holiday stuff if I'm not checking a main suitcase, since you can then get away with a Cabin bag to save money.
Checking the Golf bags last month to Turkey travelling with Sun Express (via TUI) it was £40 per Golf luggage each way. So £160 for two bags both ways. Yeah. I know. Steep. But when you pull out your own clubs on the first tee at Carya golf course under flood lights, it's so worth it. I hired some clubs out in Turkey on a different course and they were surprisingly bad condition. Another guy rented some and played off a 14, yet my son off a 20 beat him as he could not hit the clubs. So yeah. Take your own clubs.
Easyjet was about the same. £35 or £40 each way.
When you check in at the airport you get your Golf club bag checked with a tag and then proceed to the oversized baggage area. My experience was fine. Bit slow collecting at Antalya Turkey and back at Luton via Sun Express. Easy Jet were quick though. At Tenerife my clubs were sitting there before anyones checked baggage came out on the carousels.
If I were going to buy a Golf club travel bag and I knew I would travel more than 2 or 3 times, I'd probably get a hard case. It would also depend how expensive and nice my clubs were. Mine aren't great so I got a cheapish bag. I wouldn't get the £20 ebay jobs. Will likely be awful.
