Need a suggestion for booking
 

Hi,

I am from NZ and need some guidance for booking some flight
1:- I want to book a flight from NZ to Boston and I am checking skyscanner
but I would like to have a selection in which I can select departure flights from Airlines A and return flights from Airlines B
In short, I would like to have a wider selection of airlines for departure and return but I am unable to do so

If anyone can suggest me on that or some different website where I can have a wider selection like If I select Air NZ for departure I can have a choice to select different airlines other than AIR NZ for return

Thanks in anticipation

Search for one way flights:not a return
Your options are limited.
Consider separate ticket BOS to LAX or USA-Aust and a separate trans Tasman flight

Airlines that fly USA/Canada to Australia (most from LAX) are
- United [Star Alliance] (LAX SFO – SYD MEL & GUM-CNS)
- Qantas [OneWorld Alliance] (AS partner) (LAX JFK DFW HNL – SYD BNE MEL)
- Jetstar (HNL – SYD BNE)
- Delta [Skyteam Alliance] (VA & AS partner) (LAX – SYD)
- Virgin Australia (DL partner) (LAX – SYD BNE)
- Hawaiian, via Hawaii (AA & VA partner) (HNL – SYD)
- Air NZ, via AKL [Star Alliance]
- Fiji Airways, via Fiji (AA & AS partner)
- Air Tahiti Nui (last segments on codeshares) (AA & DL partner)
- Air Canada [Star Alliance]
And others via Asia & Middle East

Airlines that fly USA/Canada to New Zealand are
- Qantas via SYD BNE & MEL [OneWorld Alliance] (AS partner)
- Virgin Australia via BNE MEL & SYD (DL partner)
- Hawaiian (AA & VA partner)
- Air NZ [Star Alliance]
- Fiji Airways, via Fiji (AA & AS partner)
- Air Tahiti Nui via Tahiti (AKL) (AA & DL partner)
And others via Asia & Middle East

Booking two one ways will be significantly more expensive than a roundtrip ticket on one carrier or alliance.

If you want to travel on different Airlines (which can be also done on one ticket, as long as you stay in the same Alliance like outbound on Air NZ, back on United) try Kayak, Google flights, Expedia etc. A lot of them will show you Alliance wide tickets, often ticketed on a codeshare (i.E. it looks like a NZ ticket all the way but certain legs are operated by another carrier like UA)

If you want us to help you out it would help to specify the dates you are looking at and the budget you have.
