Thanks for all of the comments.
You should be OK, but may have to keep your tote on your lap
That would be okay with me!!
Ask Mom to please pare down her stuff to a 21" TravelPro swivel wheel bag too. If my wife can travel indefinitely with the same bag and a oversized purse, so can she.
Unfortunately that's not going to happen.
Yes, this luggage is perfectly manageable for the three of you, even if you need to handle your mother's checked bag. Do ask that she keeps the weight of her 25" down, but I suspect she's mostly packing clothes in that bag.
I will definitely encourage her to keep it packed less.
I'm glad to see you are checking your bags. It makes things so much easier in the airport. You might want your mother to have a very small underseat wheeled bag so she can manage her personal item in the airport unless she can manage with just a light purse. The airport hike and wait can be tiring. If she does get a wheeled underseat bag, she might find she can downsize slightly on the checked bag.
Yes, we are each checking a bag. So the idea is all my mom will have to do is walk through the airport (we will carry her tote). And then when we get the checked luggage, my sister and I will continue to manage the bags.
You have too much luggage for the average taxi. You are correct in that the average taxi is smaller.
I appreciate knowing this. Which means I need to be prepared to have us use 2 taxis. Better to know in advance.
Your mother needs to be more understanding of what problems her luggage size will cause you and your sister. A 25” piece of luggage is too large. Her luggage will be a huge liability no matter which way you travel, taxi, or car service.
I appreciate your input and I'm glad to know in advance that it will make things difficult.
I am not going to comment on Mom's luggage but 3 people and all that in a taxi is going to be a strain unless people are prepared to have bags on their laps (if allowed). Ensure the car service knows size and quantity of luggage
While I haven't booked the car yet (that's another post, LOL), when I have looked into booking they all have a way to note the quantity of luggage.
I'm a firm believer in packing cubes and the "ranger roll" method of packing them. if your mom does that, I bet she finds she can fit more clothes in a smaller bag.
I love packing cubes as well! Yes, she has the ones from eBags, the same as me.
I appreciate everyone's input.
For those who have noted that the 25" suitcase is too big, am I really any better off with a smaller roller (the same as mine), but an additional small tote for my mom? I could probably get her on board with that.
